I'm not sure whether this fits the technical section better or the non-technical one. It's a bit of both.
We need to do something about the n-word. Ideally, we could just not ban for it, but I'm guessing you're still not allowed to do that.
If so, perhaps we could filter it out in a fashion similar to lime? Just replace all occurrences of the word with an empty space, "[CENSORED]", "e", or "lime". That way there would be no need to ban someone who just carelessly typed the word in without thinking about it (or without knowing about the rule), and if someone would consciously circumvent the filter (lol lemon), banning them would be much less controversial.
