I mean... do _you_ have any ideas about how to fix this sort of thing that would survive being published for the world to see?
I don't mean to offend you or anything, I just want to point out that the second you go public with your rules about how these things are detected, the people you are targeting will adjust their behavior to evade them.
I think that the secrecy is unfortunately a hard requirement until perhaps we could all coordinate into a global "behavioral score" system. And to be honest, that sort of shit is terrifying, so we should probably never do it.
