Humans are basically symbolic representation generating machines. Trying to stop such a being from communicating ideas by limiting their available vocabulary in a particular language is short-sighted and massively underestimates humans in general. Maybe that's a fancy way of saying that the only thing that scales with the community is the community.

have you never played video games?

sure lets votekick someone from club penguin, im sure that wouldnt encourage cyber bullying and make matters worse

I've played a bit of https://skribbl.io/ recently and the votekick mechanism works very well for getting rid of people who just want to draw dicks and write swear words.
