1. On your vendors don't say why they took action point. I think a lot of vendors, us included, worry about the bad actors knowing the _how_ of our algorithms because they will then have intelligence on what to try and work around to avoid detection. It's a constant adversarial chess match we adjust, they adjust.
2. As for the human element being needed for the after effects I totally agree. That said, I looked at our numbers and while many of the nefarious actors simply move to the next thing, a very large percentage of the, "WTF" replies are actually from bad actors hoping that is enough to be re-enabled and to keep going for a while. Our goal is to bring more people into the after effects and give them better information to make decisions and work with customers to avoid this kind of mess in the future.
I have had friends who have had their Twitter or Youtube accounts shut down with no explanation from the companies involved. Just recently, MailChimp shut down a brand new account for my SaaS (we had only 4 subscribers added, and hadn't sent out any email campaigns yet!) with a refusal to give us an explanation why. We set up another account and did everything exactly the same way (including tediously replicating lots of email templates manually) without the same thing happening. Why was the first account shut down? We will never know, it seems.
I am all for using AI to detect dark patterns and raising a flag, but I think these companies need to bring a more human aspect into the after effects. Surely a legitimate operator will always email in with a "WTF?" whereas a nefarious actor will simply automatically move on to the next thing?
