Ban for an insult? wat.
A pretty tame insult at that. Maybe it's because I"m a "yank" but 'your mama' jokes are so common and harmless over here that anyone older than 8 wouldn't take offense. Maybe this is a new cutting-edge insult in other places though.
Anyways, if I was king of the CRPG world and had admin rights, I would punish those who break the rules. Skirting the rules and being a incessant nuisance isn't breaking the rules. Quite the contrary, it's what distinguishes CRPG as an outstanding community with the most diverse and colo(u)rful characters out there. That is, until they make us all wear ties and face forward, and order us not to deviate.
Fight the emerging police state!!!!
