Some large companies even flagrantly violate the extremely lax rules that exist in the States. Guitar Center has infamously been sending me emails that are in direct violation of the one click unsubscribe regulations for almost a decade now. I can’t even sign in to the account to cancel the emails (which is in direct violation of the regulation- it is ambiguous on a lot of things but the one thing that it isn’t is that you aren’t supposed to be required to log in to opt out of email communications) because it was made with my dad’s email from 20 years ago yet I’m the recipient of the spam.
I did report them; but of course nothing must have happened because they are still doing it.
The LinkedIn way.
And then there's those online stores that cover the entire page in a popup that you can get a 20% discount code if you give your email. Technically I've opted into their marketing. But I always just use the coupon and then report the email as spam without bothering to unsubscribe.
Also there are separate email marketing laws.
Referring friends and family by sending emails on your own? Who the fuck does that since ~2010? Ever heard of social media and instant messengers?
Edit: Parent was a wall of text when I responded. Stealth editing it to something completely different is not cool.
Social media MAY be an exception, but that's because people are already used to receiving a ton of spam on it, so your "viral post" will be ineffective to begin with, and probably filtered by Facebook and not shown to most people at all. Enjoy.
All the original social platforms such as Facebook and Twitter used ways to invite others by email (famously in Harvard etc.) So now they are burning the bridges behind them and no one can do it anymore.
(An attacker used the paypal guest account feature and used my IBAN [european bank account number] and tried to hide the mail within those hundreds of mails. They were successful for some days, until the purchase showed up on my bank account)
A few times I've had unsubscribe links absent or not working for whatever reason and done that and a human's replied and sorted it out.
