But man, I don’t envy companies deep in the anti-spam/fraud business. The impression I’ve gotten is that when you act with a lighter touch and/or give lots of info about why an account was closed, spammers/fraudsters weaponize that and either figure out how to bypass your controls or social engineer your support.
I hope I’m wrong. Any thoughts on how a company should balance good service to users (and false positives) with the need to fight black hats?
