yo so everyone who downvoted you dont get OP's question.
OP is basically asking, If somehow a hacker made enough bot accounts that COULDN'T be detected, and these bots outnumber the actual player base, What would happen?
IE: say saying the word "nice job" is considered fine, but then these bots are introduced and suddenly everyone saying "nice job" is being reported.
This is a thought experiment guys do some thinking!
My thoughts: if the bots existed and outnumbered players, in order to to ban people for being toxic theyd have to you know.. talk. so we would see players just accepting that chatting is now no longer safe, and the game would go on as normal
