If I were admin on our server and someone used a name like that I'd probably kick/ban them... would depend on my mood at the time tho and would say something to them before doing it.  Not in the context that certain words offend me but words do offend most people in my experience (United States of American retards tend to have many problems with many trivial things like words and boobies and butts) and usually if someone uses a name with offensive words they're deliberately trying to offend IMO.  I see it like poop.  Someone comes into my house and poops on the floor, I'm gonna kick their ass... unless there's a good reason not to.  Take BitchKiller for instance.  He's incontinent from taking it up the ass all the time so it's hard for him to control his bowel movements.  I just make him clean it up or rub his nose in it :)
