The naming policy (www.worldofwarcraft.com/policy) was changed last year. Those type of characters are NOT a violation any longer. It's just not in the policy anymore. Did you get an email from wowaccountadmin@blizzard.com? It should state what you were suspended for.

You might want to check the support page (http://us.blizzard.com/support/artic...l&pageNumber=1) [I even did the search for you] to make sure you'll receive email from them. Worst case scenario, send an email to AA yourself to find out what happened... you can dispute it through them if you shouldn;t have been suspended.
