Other Examples of Craigslist Spam Tactics [NSFW]

The results for spamming adult dating affiliate links was pretty interesting. On average it would earn $1k a day, with most holidays jumping up to $2k a day. One very religious holiday in particular (won't mention which one to single any group out) brought in $3k. In one single day.
As long as spamming people with affiliate links will work, and makes them money - someone will do it.
Craigslist puts in a lot of effort to warn people about common scams, yet the problem persists in the high-value categories. This is especially true of rentals -- I get a Google Alert every week of Craigslist-related crime appearing in news reports, and half or more are rental scams. How can people miss the warnings and get conned? Part of the reason relates to smart social engineering, as the OP suggested -- girls, convincing sob stories (active duty military deploying overseas is a common hook), well-written emails, great prices that are almost too good to be true. The scammers are constantly running tests to see what works best and then applying them to multiple areas. But the other thing is the nature of buyers, who may only come to Craigslist once every few years and may assume that because their last experience turned out good, their next one will, too.
On the spam front, "flagging" is one of the main weapons CL uses to fight things like overposting, top-posting, miscategorized posts, etc. Unfortunately the system has broken down in many markets. Check out some of the cities in Western Canada, which are overrun by spam (see "Craigslist Canada: Ticket spam, giant markets and dead areas" http://invantory.com/2012/04/craigslist-canada/ ). Dealers and spammers using manual or automated means simply overwhelm the categories, and there aren't enough active flaggers to mark the violators -- or people have simply given up.
Classified marketplaces really interested me, and if anyone wants to talk about Craigslist or mobile classifieds, I can be reached via the websites listed on my HN profile.
The real world rewards are huge. I know people who have sublet a place worth $5k USD/month from someone for $2.5k USD/month because they hunted for a deal and found someone who had to go move and take care of their parents ASAP and that person didn't have any other immediate takers pop up so quick.
What AirBnB did was a little spammy (and probably violated CL's ToS). Same goes for ODesk and other freelance boards (I got one from HireTheWorld just the other day).
When someone wants all your personal information or help moving (i.e. "laundering") money overseas, that's an entirely different animal.
Lots of companies use affiliates to do the dirty work for them, then ban affiliates that get caught. New affiliates pop up, or the banned affiliates create new accounts and start over. That leaves sites like Craigslist in the unenviable position of playing whack-a-mole to try and ban spammers.
Other variations on these include fake profiles of women on (insert social networking site her) who inexplicably "friend" men and entice them to sign up for dating/adult sites where the target can see more photos, and gambling instruction guides/beat the casino secrets uploaded to torrent sites for free. Naturally affiliate links to lots of online gambling sites are embedded in the guides.
I guess the takeaways are:
1. Never trust user generated content.
2. Whenever there's a way for people to produce content (effectively) for free, the affiliates/scammers will be there. I built a rental-listing site a few years back. Not long after I stared getting real listings, I started getting rental scams. I had almost zero traffic, but the tiny blip on the radar screen my site produced drew scammers like flies.
4. It's often better to ask forgiveness than permission. What repercussions did AirBnB suffer for their posts? What real repercussions do any of the spammers face?
5. Just writing about affiliate marketing, well, at least this side of it, makes me feel icky.
It's worth pointing out, that if you used some sort of standard back end like Wordpress or some other user content system, there are bots built to search the web for those and post to them automatically. I wouldn't put it past someone to throw in a check for if it is real estate related and handle slightly more advanced back ends like Drupal.
I did have a Pligg site I put up as a quick project and that was a victim of the automated searches for the "submit" page of a Pligg site. Even adding a CAPTCHA didn't help, so I assume offshore workers were adding links manually.
I definitely consider them different, though perhaps I didn't highlight that difference sufficiently.
I made a modification and titled the section as such, with a credit to you in the post.

That seems to raise a broader question, which is: to what extent should companies be blamed (and thus try to control) for the actions of the people in their affiliate programs? Would you be unhappy about a blog purporting to be by a cute ice cream eating girl filled with recommended books with Amazon affiliate links? What are the standards in this area, exactly? (On reload, see dabent's comment below as well.)
i.e. if someone includes <a href> inside the email body, simply unscramble it and show the full link.
And on the bottom of the email spell out a warning about affiliates.
This will eliminate most of the spam that goes out to people who list stuff on craigslist.
To fight spammers that list fake listings to gather email addresses...simply implement a private message system for craigslist. Then you can analyze all emails that get sent to users and do the same trick as #1.
You can also limit exposure by blocking messages based on user IPs. Chances are someone from China listing in New York craigslist is a fake.
Craigslist already does this to an extent in their high volume categories. For example, one cannot post Job Listings in highly populated areas (like New York or San Francisco) unless the posting IP address comes from a place near there, and the account is verified via a phone call. Anyone not fitting this description must pay a certain amount of money.
The other side of the coin is the blackmarket selling of Phone Verified Craigslist accounts along with proxy lists in those same markets which can effectively bypass any IP filtering put in place.
That last one would probably just create a minor inconvenience for actual scammers while creating headaches for the occasional legit "I am in Shanghai please buy my couch" poster.
Wish the final pic had a NSFW warning though.
I now avoid any car with steering wheel covers in the picture as all the wreck scams I've seen had them.
Safer to miss the few false positives.
Clean it incredibly well.
Put a steering wheel cover.
Sell at Glendale for 6k to 10k as if it's a private sale.
