Interesting. Does “mongoloid” on its own mean someone of low intelligence? We have mongoloide in Brazil with that meaning. More often used as a way to call a friend silly instead of an actual insult, but can be used as one too.

I can absolutely see that happening. Perhaps only allowing edits for a limited time after posting or only before a certain number of interactions (votes / comments) can be a reasonable way to allow edits but prevent abuse

This sounds like the beginning of great tifu post
