So let me start of by saying, that whilst I've rolled on an RP server, and enjoy RP'ing, I'm not a super scary angry RP'er and if you want to name your character something stupid, while I'd prefer you didn't, it's up to you and I'll just suspend my disbelief.
That said, yesterday I met a guy who'd called himself Revaan (seemed like a nice guy otherwise though ), and seriously? Is the naming filter THAT easy to beat?
