Yes, either the GMs ( or whatever, not quite sure what these omnipresent beings like to be called in this game yet ^^ ) got a complaint, or deemed your name to be offensive just by looking through the character list. If you are not happy with your new name, I belive you can ask them to let you re-name your character, albeit, with a non-offensive name fitting the fantasy style of the game. The naming rules are outline on the offical EQ2 page below.
