Simply put, Mir is a social game, can be a family game if the community wasn't atrocious, the idea is, it's public, you watch what you say in public or you get judged, I'm sure somebody felt strongly enough to report bad behaviour or offensive names, and as a business they need to keep the customer happy, especially if what they're asking isn't unreasonable because the idiot behind a keyboard decided to call himself JihadJohn or something along those lines.
If you act like a tw*t and you get pulled up on it, accept the consequences, sick of all the moaning on this thread about the GMs sense of humour, it's a business plain and simple, so deal with it.
