Sanya Thomas the Director of Community Relations for EA Mythic has posted the following at the War Herald:
I keep getting these weird emails, asking if it's true that anyone associated with a website using a bad domain name will be banned from Warhammer.
That would be stupid, if it were true. Good thing it's not true.
Customer service bans from any EA Mythic game are related to in-game actions. What you do out of the game has nothing to do with your in game account. Also, I feel like I should mention that it's September 2006. The earliest you could possibly be banned from Warhammer is more than a year from now. Relaaaaaaaaaaaaaax.
So no bans... yet...
