Block: Inflated user metrics and “frictionless” fraud facilitation

I could easily believe that they are not doing their KYC work and that the feds will soon make them do so, but it doesn't really seem to add up to the company being a "fraud".
Which, to be fair, the Hindenburg headline doesn't say, it's "Block: How Inflated User Metrics and “Frictionless” Fraud Facilitation Enabled Insiders To Cash Out Over $1 Billion". Facilitating fraud (by not doing enough KYC, etc.) rather than the company being a fraud.
The allegations in this report add up to wilfulness. That could result in the company’s money transmission licenses being revoked.

page 74 of their 2022 Q4 10-K shows a per segment (between Square and Cash App) breakdown of revenue
If you voiced any concerned you were silenced and eventually terminated.
I also worked at Block until earlier this year and AFAIK, the % of Block's overall operating costs spent on Bitcoin side projects is very low. Maybe 1% or something like that.
I noticed one day that my books were off (down) by 1 penny. When I dug into it, I figured out that Cash App is providing their customers with conflicting reports for their stock sales.
In the app, the sales report rounds pennies up, in the actual sale, whose records are only available through more complex data export process, the penny in the sale is rounded down, and they are keeping the difference.
I found the rule in the legal terms which states that the calculation in the app presented to users is the correct one, and the penny is illegally missing.
This is for every trade for every one of their users. The aggregate amount of money is huge.
Edit: I just looked back at my analysis and now remember in some cases the missing money is more than one penny. If anyone would like to contact me one on one I can provide more proof.
This is a fuckin dog boarding company I work for, not a bank. Because no, you can't screw your customers a half penny at a time... it's on you to fix the accounting and make it right.
Both are bad, one is far worse.
The issue isn't that it was executed at a higher price than expected or that it was "rounded up" in general. The issue is that for a single completed transaction, in one place (general app UI) it is reported to have executed at one price, and in another place (the data export process) it is reported at a different price.
Which is, of course, “swordfish.”
> There is no legitimate scenario where they would be reporting the Net Amount for the same sale in two places with different numbers.
The net amount reported in the app isn't an estimate, nor is it ever updated.
If you do the math, the amount listed in the app, according to their own report, is the correct amount. The final asset price X the final asset amount, as frozen in their long-term reports, is the amount listed in the app.
There is no hand-waving financial explanation for this discrepancy.
> Block isn't running some elaborate Office Space style scam
I have black and white evidence that they are. Stealing isn't necessarily elaborate. I'm surprised you find this hard to believe when TFA is a report about other types of fraud by the same company.
> how little techies know about banks and trading and the financial system ... There is a lot of complexity behind the scenes
Your comment is a little condescending, I don't think it's a big secret that trades get settled.
Or could it be that the number in your bank account is consistent with what the buyer/seller on the other end of the trade is getting?
There are three key numbers here: the net amount reported in the app, the net amount listed on their buried report, and the amount paid. The net amount in the app is correctly calculated according to their own report of settled asset value and amount. The net amount in this buried report and amount paid do not match that.
Since these numbers again, are not estimates and never change, including after any settlement period, there is no legitimate explanation for the discrepancy.
You mention audits as if audited companies never commit financial crime.
This year's gonna get real interesting.
What do you mean by this
The main thing they get from offshoring the driving is scalable renting of capital. But well, I have no idea if one could not just rent it without the labor.
The other half is that they used nearly free money provided by the US central bank, routed through VC firms, and engaged in anti-competitive predatory pricing.
The pricing issue is stark and impossible to miss. I produce events for a living and I'm in a different city every week. The cost of an uber ride now is invariably 2-3x higher than it was a few years ago at minimum sometimes 5-10x higher.
I remember tooling around Chicago and getting fares that were like $2.17 and $3.22 a couple years ago. Any fares within downtown Brooklyn were $8, period, often discounted via a promo to $4-5. Now they're routinely $25, maybe $15-18 on a slow day.
That's where all the VC money went, and it simply wasn't possible to compete with that unless you had access to all that free money too, which local business didn't.
Revel, in New York, has employees and does fine.
Then Revel does fine.
They’re not, particularly since “spending and losing VC money” is often tossed around Uber, which doesn’t make sense, since it’s no longer VC backed.
I’m interpreting your sentiment as having a cash-flow positive operating model. Ridesharing absolutely works on a fundamental level with enough gross profit to fairly compensate drivers. (It doesn’t if drivers can log on and off at will, nor in low-population density or poorer areas.)
https://www.wsj.com/articles/new-york-city-commission-thwart...
You claimed the “moment that [ridesharing companies] have to start treating drivers like employee's they can't make money.” I showed a counterfactual. You’re doubling down with hunches and suppositions.
> Revel NY ridesharing isn't going so well
You’re citing an article from 2021 on the TLC blocking Revel’s application for more vehicles [1]. (It was since approved.) How is the government telling a company to stop growing an indictment of their business model?
[1] https://www.wsj.com/articles/new-york-city-commission-thwart...
For drivers, yes. But in many cities the taxi system was engineered so that the owners of "positions" got lavish profit.
WeWork is a real company and managed it for a while
So the question (if we suspend judgement of these initial tech waves) is: if ignoring and bypassing regulations to introduce new approaches is also broken, what is the solution to the original problem? As an illustration, examine a hypothetical of when or if civic centers would themselves modernize transporation for hire regulations, mechanisms, etc.
I would say nearly all of Silicon Valley tech startups. Around 90% them are a complete SaaS grift and are also eternally unprofitable and are very good at losing money.
Hence why they are solely dependent on begging for VC money every month to pump the pyramid scheme that recently collapsed a week a ago. We saw which startups were affected and would have instantly been bankrupt had it not been for them beggeing to the government for a totally-not-a-pseudo-bailout scheme to 'save' them.
To see who was caught in the fallout, we needed catalyst events such as the start of the market crash in November 2021, the collapse of crypto in 2022 and now in 2023, a large tech bank (SVB) becoming insolvent and failing.
> It's incredible that since 2008 it actually seemed immensely easier to skirt regulations and laws (under the banner of 'innovation'), and not just in finance.
Now the grift has continued to spread into the AI hype squad with everyone and their bots spinning their own ChatGPT SaaS startup. Don't be surprised to see them falling like dominoes since the real winner in this AI hype is OpenAI. Not the startups built around it.
I haven't seen any particularly strong profitability case for ChatGPT and the like yet, unless you call ad dollars from promoting "ChatXX does this amazing trick!" as proof.
People barely even questioned the ludicrous wages being thrown around in silicon valley, supported by 'funding rounds' and silly valuations of future growth.
But, it all sucks because the people that will lose are the last-in-chain investors and the to-be-unemployed. Not the VC crybabies currently out there complaining about their need for protection by the establishment they protest.
Until I moved, I earned five figures, you know a bit more each year, and was happy. I had a house, a big spacious house by San Jose standards, and a nice town with friendly friends and so on. When I started in SV, they raised me to USD 120,000 and the HR recruiter literally apologized for it not being more. Since then it has gone up about four x, for no really good reason that I can see, since it is fun work I would do for much less. Only when you get into profit per worker does it make sense.
And that isn’t due to some moral failure entirely, but something about the weird asymmetries that networked technology seems to facilitate. One little neighborhood, but services and products for dozens or hundreds of countries. Each time a country is added to the network, the winner takes some more.
Hindenburg made a music video compiling the references that is...uh...worth watching: https://www.youtube.com/watch?v=StjWk3Mj-M4
A scam here in Baltimore that keeps occurring is that the squeege kids will run up on someone unsuspecting and start cleaning their windshield.
They will pressure the driver for a tip, and the driver will say they don’t have cash of course.
They will say that’s cool, you can send me a tip. They ask the driver for their phone so they can look up their cashapp for them, and bam the driver got scammed.
What’s happening is that the squeege kid is looking up his account on your phone, and then sending himself like $2,000.
People have complained that cashapp won’t help, and their bank isn’t letting them dispute the charge.
In my opinion, this is clearly an anti pattern on Cashapps end, and I would imagine at least one engineer would have spotted this vulnerability by now. I would think that Cashapp would build in a simple pin confirmation before a stranger could wire themselves a couple thousand dollars. This has bugged me for the last 2 years lol
If you get aggressive, they will spit on your window, break your wipers off, and hit your car.
Things can get really ugly if you get out of your car and try to confront them: https://www.thebaltimorebanner.com/community/criminal-justic...
A bunch of their transaction volume is scam money that is hard to reverse, and it’s not Blocks fault as you say.
It’s a negligent move for sure, but a crime is still a crime.
Having someone steal your money without your consent is still theft and they are still the perpetrator of the crime.
The victim-blaming mentality on the internet is wild. Being negligent or naive doesn’t shift 100% of the blame to the victim when a crime occurs.
Two things can be true at once: the perpetrator of a crime is the one responsible, AND the victim might have avoided victimhood had they acted more prudently.
Humans communicate in stories. The “cautionary tale” or example of folly that led to woe is a pattern as old as our species could talk.
It is NOT true that cautioning people not to act imprudently, and providing an example, is “victim blaming”. I don’t hear anyone saying that we should not pursue and prosecute the perpetrator.
So just can it with the hair trigger “victim blaming” accusation.
> caution others to behave wisely to help avoid being victimized in the same way
In this case though this is not a caution to others, it's literally a statement of victim shaming/blaming.
Nobody is claiming the criminals are blameless or that a crime is not a crime.
It's astoundingly dumb to hand a piece of electronics worth several hundred dollars to someone in such an interaction, even if they cannot use it to electronically steal your money.
The criminal is a criminal, and the person who hands their phone to someone under these circumstances is mind bogglingly naive. The former fact is tautological so it's natural to focus on the latter part, the one that boggles the mind. How could anybody possibly fall for this? Were they very young? Were they old? Were they distracted or drunk or lulled by the perpetrator? Were they out of towners? Were they intimidated? One wonders.
It has nothing to do with Cash app. It could just as well be Zelle, or PayPal, or Venmo, or physical cash.
The link's whole thesis is that Cash App doesn't really care, which is why criminals prefer it. Being so radically frictionless for the underbanked also facilitates scams, including those that distinguish between theft and fraud.
I'm not familiar with this situation, but I'm assuming that whoever is doing this isn't there to "clean" your windshield, and that the entire "transaction" is imbued with the implicit threat of violence and intimidation. You're essentially being robbed through other means. If this isn't the case, then I'm happy to admit that I'm wrong, but that's how it reads to me.
Someone tried to sell her a rock at a traffic light. When she wouldn't buy it, they used it to smash her rear driver's side window and grab whatever they could from inside the car.
https://news.gallup.com/poll/264932/percentage-americans-own...
over two million background checks for firearms purchases are performed each month, and this number is rising, and the number of people who are being background checked for the first time is rapidly rising (fastest growing group - black women)
by 2030 there will likely be a half billion firearms in the US
there are more fully automatic rifles registered to individuals in Texas (40k) than are in possession of many NATO armies...for semi-auto pistols and rifles, Texas residents outgun most NATO armies by a substantial margin
these are stats that both gun advocacy and opposition groups will be happy to validate (each believe the numbers support their position)
anecdotally, it is very common here in Texas to read of traffic altercations in which both parties involved in road rage incidents were carrying in their vehicles...it is widespread
Also according to the Small Arms Survey, Texas has five times as many guns as the US military.
Though the US military ones are more likely to have select fire and fully automatic but those are only particularly useful in certain situations.
Not really. By the time a seat-belted person gets to their gun, whether in a holster, under the seat, in a purse, or in the glove box, the thief is long gone.
Real life is very different from the movies.
I remember a few years back there was some controversy about how police are trained to shoot first and one of the things that bubbled up then was a video (I think produced by someone teaching the police) of a seated driver drawing a gun and having it pointed out the window in a fraction of a second. The gun was in a holster down by the seat belt buckle. And the next instant it was pointing out the driver's window.
Joe Lunchbucket isn't likely to be so agile.
not in the US - millions of people keep loaded guns in their vehicles
> During the Coronavirus pandemic, the number of concealed handgun permits has soared to over 21.52 million – a 48% increase since 2016.
Given that some states are "constitutional carry" (21 states) and do NOT require a permit if you legally own the gun, the actual number of people who HAVE a gun and can carry it would be higher than 21 million. They even do the math:
> To summarize, the total number of permits in the US is at least 21.52 million. Add in people who legally carry without a permit, and the number clearly becomes much larger. While 8.3% of the adult population has permits, the percentage of Americans who say that they carry most or all the time is about 5.4%.
5.4% of Americans is about 17 million people, the majority of which will carry when in their vehicle. (Note that legally and technically you are "conceal carrying" in many states if the gun is IN the vehicle, not locked, even if it is NOT on your person - so if you're married and YOU carry, you will want your spouse to get a CCW also even if he or she never carries, because if you're both in the car, the gun is in the center console, and you step out to get gas, your spouse is now concealing).
I want to live in a world where I can trust a random stranger, not suspect them of robbing me. Justifying some extra protections like a pin or a fingerprint check to finalize a transactions should not be this big of a deal.
They are all actually pretty intelligent individually, and they come up with some pretty clever things to get into. A bunch of them come from rough homes, and they are usually taking the cash home to support their family, even at 15. They are supposed to be in school, but they skip to go squeege because they don’t feel like the things in school are relating to their struggle. They have tried the regular 16 year old jobs, but that doesn’t pay enough to cover their struggling mom and siblings. Instead of losing out to low wages and income taxes, they find it much easier to pick up a squeege from a gas station, and start making some instant cash in tips.
These kids are super smart lol. Pressure breeds diamonds. They know how to hack the Lyme scooters and ride around and commit crimes. They know how to scam you out of your cashapp balance. And they really know how to download and build burner handgun kits from Defense Distributed :(
If somebody chooses you, you're not choosing at random.
Let's simplify. Say that 1 in a million people pull the stranger needing help scam, and will approach you given the opportunity. Everybody else will only approach you if they actually need help, which is rare, say 1 in a million.
So in that scenario 50% of the people approaching you are criminals, compared to 1 in a million who are actually criminals.
This is and always has been utterly delusional.
I think this might be an actual generational difference; I feel weird letting someone else use my phone or using someone else's phone now. I can remember a time when phones were much more communal - the family shared a phone, and public phones existed, and I wonder if older folks are a bit more locked into that way of thinking. Obviously a phone is much more than a phone now however.
On the other hand, my phone causes ringing on my phone, my IPad and my work laptop: for the love of G-d don’t just watch it or tell me it is ringing, answer the damn phone. U less it says likely scam of course.
A guy did exactly what you said, and they snapped his wipers off his truck. He parked highly upset, and stepped out with a bat to confront the kids. One of them pulled out a handgun and shot the dude down right in rush hour traffic.
She lost her job, and the city started enforcing a no squeege ban.

Your mentality is typical of people from low-trust societies - "lol those naive Westerners" (lokhi[0] in Russian). But while individuals in high-trust societies can indeed be lokhi, everyone in a low-trust society is, collectively. They are giving up on the social development and institutions that only work well when trust in people you don't know is a societal value. They are defective at best, and nonexistent at worst, in a society where everyone treats each other with scepticism, disdain and distrust by default, until proven otherwise.
[0] https://russiapedia.rt.com/of-russian-origin/lokh/index.html (sorry for RT)
Thing is, it's not the case. The world outside of a narrow circle of rich, white, Protestant countries has never been like this, and those countries too, are losing it because of changing racial composition, and immigration from low-trust cultures. And in a global world, high-trust groups are simply being taken advantage of.
Honestly the fact that some govt employee in india got so much right that all the sv startups could not is truly baffling.
Right now, muggers can't take $1000 out of my wallet because I don't have $1000 in my wallet. They cannot force me to use an ATM to empty my bank account because my ATM daily limits are set to $500/day.
But, in theory, they could empty it if I was on Cashapp.
Cashapp, like so many tech startups rushing to replace incumbent taxi and hotel and other services with phone apps, has missed Chesterton's fence on this state of affairs in its hurry to become the key part of "providing everyone with access to important financial services so they can fully participate in the economy."
When I moved to california my debit card got skimmed at a Lucky grocery store. Ever since then I've made sure that my debit card, venmo, paypal, and all my other money accounts are linked to a checking account that only has $500 in it. If I need to transfer someone more than that I'll transfer money into that account from my real checking account.
So, just avoid CashApp and Zelle.
And another euphemism.
This is the 12th reply to your post and first one to point this out. I think this report is trying to ride well-off people's lack of awareness of CashApp. Kinda what they're accusing Block of doing, which is funny.
And then there is also the racial-related aspect of it all, not sure the Hindenburg analysts were aware of it. As in there is no white rapper in that video of theirs.
Block targets Black Americans. This is like complaining about a gardening company’s analysts only talking about gardeners.
Even worse. So one of the companies that tries to address/serve the black demographic is being put down but what I assume are not black financial analysts.
Like I've said, this Hindenburg company seems to not be aware of the whole societal background.
This sounds like Adani’s defenders getting mad about Hindenburg not being Indian. Fraud is fraud. Their specialty is fraud. Why is fraud okay or not depending on who’s committing it?
The intended outrage here is "ghetto males" doing illegal things with money, using the cell phone, and bragging about it. The parent post here points to major just-under-the-surface problems with this kind of personal, borderline racist attack at the societal scale. Definitely concur here that a perfectly-enforced police state is not desirable, mostly because it is not possible, and the more force that is used in the remaining edge cases, makes things much worse overall, at too high a cost.
On a more general note I'm also curious about what you mention at the end of your comment, i.e. those higher societal costs are keep piling up, I'm wondering where is it all going to end.
Indeed, white rap artists are very underrepresented in mainstream popular music. There is a case for it being discrimination based on skin colour.
</s>
The fraudulent activity is obviously a problem, but I'm not sure how to separate this association from, say, bragging about buying Gucci with drug money, street racing in a Dodge Hellcat, or performing drive-bys in a Revel.
And indeed for any luxury brand that exists. I still don't understand how that makes the app itself a fraud.
This is marketing not moral reasoning, and as customers, please encourage other customers to have a low tolerance for being blamed for fraud.
1. It's visual and memorable.
2. It leaves you wondering what the hell Dorsey and "Cash App Studios" were thinking when they promoted these guys.
3. It strongly bolsters their case that Block were asleep at the wheel with respect to criminal activity, probably intentionally.
We all know that Silicon Valley firms are obsessed with not being racist but didn't anyone there wonder what the guys were rapping about for even a second? Or why they'd name an entire song after the app? That isn't in any way normal behavior for rappers. Surely someone watched it and realized that, um, this isn't actually good PR, these guys are saying they use Cash App to pay for all sorts of criminal activity. Why? If it's once to make a rhyme then it's an artistic choice, if it's >1000 times that can't be a coincidence.
To be so blind to activity so obvious that you're literally boasting about it on stage in front of a bunch of bankers implies a massive breakdown of AML obligations. And that would indeed be short-worthy.

CASHAPP: xxxxxxxxxWhoever had my card used it for CashApp transactions (I didn't even know this was possible?), ultimately creating ~15 transactions of varying sizes, all less than $100. It took a while to unwind, and in the end my case was actually denied (!) for 1 of them.
I bet I counted as a new user, with $100+ in transaction volume. :)
Just because of this interaction, my disposition towards Cash App has tilted into the negative, and I literally didn't have an opinion on it before. Regardless of any number-juicing they may have indulged in, their fraud-detection tech has to be better, it's not doing them any long-term favors.
I don't think this necessarily means that 40%-75% of the accounts on Block's books were fake (as I took it to first mean from the summary). Could it just mean that the accounts that were set up for review based on high risk activity were predominantly fraudulent (as they should be)?
The market is overreacting because of Hindenburg’s past successes, but the stock price has already recovered by 10+ points since this morning and is rising. I predict all of it will amount to nothing in the end.
> The Artist, “22Gz”, Was Later Arrested for Attempted Murder
It astonishes me how many rappers do this. It’s one thing to be a criminal, and it’s another to rap about your crimes and do the job of the investigators…they probably think it makes them tough or something.
That said this really seems overblown. The report seems to mostly just talk about Cash App. Square Payments, Weebly and TIDAL are not even mentioned. Afterpay is mentioned but that was a 2022 acquisition so the problems likely predate Block's involvement.
It feels weird that they're using Cash App to indict the company as a whole. A single product in their portfolio doesn't justify calling the whole company a fraud.
they profit off shorting. So it makes sense to target them if the company has _some_ issues with fraud, even if it's a small part of their business, as it hasn't been priced in yet before this news breaks and people are positive about the company.
They aren't doing a public service or anything. It's a reason why companies like credit suisse don't get targeted by hindenburg, because the market has almost priced in all of the fraud, and the shorting opportunities arent really there.
Block’s main product not only overstating its numbers but also wilfully facilitating money laundering and fraud could be a company-ending problem.
Can we do better? HN could be so much better.
Cash App is 60% of their revenue.
They're not saying the company is worthless, they're saying it's overvalued currently because most of its current share price is a result specifically of Cash App.
Their proposed actual valuation is quite a long way from zero and entirely consistent with them thinking the other products are at least somewhat solid.
(the title on here could probably do with editing, but that's a separate matter)
Uh, the price at rebrand was 194.50. The price at close yesterday was 77.46. That's a 60% loss, not "vast share price growth".
Flouting FinCEN and other US agency regulations would be a valuable problem
Many of FinCEN’s regulations are stupid and investors bidding up shares on user metrics is also dumb, but if any investor purchased based on poor metrics then that will be an expensive problem
the regulatory slaps will be expensive either way
The interchange issue is hard to tell about its value, but looking at Paypal’s issue with the SEC can provide clues
Is Hindenburg double dipping on whistleblower reports to the SEC?
Those puts are going to pay off handsomely.
If allegations in the report are false, the traders face legal liability. If they’re true but the market disagrees with the impact, they’ll lose money on the trades.
What specific thing should the SEC be policing here?
Also, if markets don't move following such a report short sellers stand loosing a ton of money, even if they are right.
Among other companies brought down, rightly so, is Wirecard. And they played the "mean, evil short sellers try to manipulate the share price"-card hard. So, shoet sellers do have a place in our modern financial system.
I don't know, I've been asked to send a selfie and a driver license, and activate the physical card they sent in the mail to my registered address - all the usual KYC procedures.
They also did send a 1099 form for all Bitcoins I deposited to the app in 2022.
seems pretty bad if true. gotta wonder if Block was really that lax that anyone could do that, or if the authors found an exploit and gamed the system, and if the vulnerabilities have been fixed.
Many of these Jurassic-scale disasters are ones that make me wonder "Were there any adults in the room, when this decision was made?"
I suspect the answer is frequently "No."
Meanwhile they’re profiting off some 13 year old getting raped in a Motel 6.
Not that great!
No doubt in some academic tower of excellence, the arguments are tightly wound and full of data, but it isn’t propagating to the common discourse.

If I need to spend more? I move it to cash app, then spend it.
My main checking and savings accounts do not even have cards that are active. Its all cash app all the time.
Not saying they aren't doing anything wrong, just that there are plenty of legitimate uses for the service.
Isn't that the whole point of 'disruptive innovation'?
In addition, politics being what it is, with the SVB “bailout” the Biden administration will be looking for something to show that they are not coddling Silicon Valley. Throwing a few execs in jail would send the message.

It just claims that Block Inc are overvalued, that their metrics are misleading, and that their platform is facilitating fraud.

Nathan Anderson is the founder of Hindenburg Research, a New York-based investment management firm, and a forensic financial investigator that is famous for releasing reports on alleged wrongdoing by companies. When publishing some of these reports, his company profits by short selling the target company's stocks (that is, by making a bet in securities markets that the price of the company's shares will decline). If all goes according to plan, the report itself will cause the price of the stock to decline, leaving Hindenburg Research with a profit from its short position.
The first time I heard their name I guessed they were short sellers, and two minutes on their site confirmed it.
Its like with Private Equity. A part of me hates the concept and much of what's out there, but when done correctly it brings efficiency to the market.
Basically, short-sellers, PE, etc. are all just more ways of monetizing investigative journalism. They're like a 'virus' for capitalism, forcing good behavior and punishing the bad.
There's an explicit disclosure in the piece that they've taken a short position, but really, when a short seller puts out a report like this, you can safely assume that's the case even without reading far enough through to get to the explicit disclosure.
If they're right, they make money. That's what makes it worth investigating to see which companies are screwed up.
