They could just censor everything in the same way the first MMO I played did
It just replaced everything you said with something else.
"idiot" was replaced by "friend", "motherfucker" by "good boy who listens to his parents" and stuff like that xD
Ans sometimes it was completely random, like when you got "strawberry" in the middle of a word just because it contained "ass" or something.
At least it's hilarious :>
