Nostalrius Begins - Quality wow vanilla realm (1.12)

Are there any rules against using mature language for the name of our ingame characters? For example Drunkbasturd or Coldbiatch. I wasn't planning to name my character this I was just only wondering what the rules are.

It's highly advised to read the server rules (which you btw agreed on when creating an account^^)
