Banned for unknown reason.

I received a"banned" message.
The message states that I am banned until March 3rd. It tells me nothing else about the ban and for details I should go to

I need directions here. I don’t know what I did or who to contact.

Your ban is for posting a profanity Vinyl, which is forbidden by the Xbox LIVE Code of Conduct.

Neither bans nor the enforcement of the Code by Turn 10 are discussed on the forums.
