Technically though, that's the problem with any filters. You're never going to have 100% protection against insults or flames.

And my post should have said "we were correcting".. as the people I mentioned seemed to take that word as the racial slur and not the actual word.

O x y m o r o n, in whole, is probably not specifically set as banned. My thoughts are that, as you said, the second half of the word is banned and the forums are setup to block all words that have the banned words in them, in whole.

Now.. I have to agree that I think the other word isn't really the same. That's just a supposedly controversial word that shares a phonetic similarity to a word with negative connotations, but spelling (and meaning) are completely unrelated. If it was perhaps spelled the same as the other, just add a "d" or something, that might make more sense. But as it is, the one (oxytroglodyte ), is a software failure of over-sensitivity - the other is simply a human ignorance problem of not knowing the word.
