"Huge tits" but not "huge melons", "nigga" but not "niggaz"? Who wrote this thing? I think this is about 0.1% of the "naughty" words out there, and it's futile anyway (former school sys admin here, I know what I'm talking about ;) This is before we get onto the desirability of blindly blocking words like "nigger" which have different meanings depending on who is using them, ref. "my nigger", or "tits", ref. "blue tits are eating the nuts again".
