Let me check your ban history in-game real quick, but it sounds to me that you are victim of a compromised account.
If you in fact are, I'll have to ask you to change your password and post back once that is done.
Your account being compromised means that your password was/is on a site list on the internet, and thats not a good thing.
So, change your password, report back here, and remember NEVER tell your password to ANYONE.
Thanks,

EDIT: I checked your bans, and you in fact have no band on record.
