The problem is people who repeat the same thing over and over using various slurs to do it.
Exactly. That is what is happening in FF9 forums all the time.

A good example is 'gay' - they mean it in a completely negative way, because they think that being 'gay' is bad. If they said "Character X is a nigger" they'd be banned faster than you can say 'Nu.' Why is 'gay' okay, then?
Some moderators are less offended of the word "gay" while some moderators think it's totally absurd. I know one moderator who found it so annoying that one forumer used the word "gay" for offensive purposes that she immediately warned the user. Shortly afterwards, she banned that user.
