Your "insult machine" (like the name - saw it in another post) lets you write in the chat the word WHORE but masks the word WHOLE.
This bug has been here for awhile but, maybe putting it here, will be removed.
Oh, and I remember another one: awhile ago, before the merge, I saw on one of the planets which are not present anymore a player named PENISBOT. The name itself is not the best one but my observation relates to smth else: trying to add that name to Black List has resulted in a message saying that my search contains inappropriate words or smth like this (don't remember the exact message). Now the player is not present anymore so I get the well know "The Player doesn't exist".
Be consistent: if U are filtrating the search words then filtrate also the names chosen by players.
