For those who did not know, if you get banned for having an inappropriate name (which mine totally wasn't), the first ban would be a week-long, then it becomes a year-long ban for the second offence. I sort of have a clue on why my name would be inappropriate (it was Child Predator Predator), but I'm sure I have seen other accounts with much worse names that get away with it.

Also if you're banned, you can go to the Friends window and change your name there. It wouldn't change the community profile name, but it changes the name on games.
