I don't think they ban you for joking, rooperi. They could close your account if you are too wild, but they wouldn't put your name on the cheating list in that case.
You think they had the time for a proper analysis and evaluation before banning? Especially if he was cheating for the odd move it would be impossible to tell.
They just banned him on what he said, joking or not.
i don't know scot but what you say doesn't make sense either.
Perhaps he was winning against erik?
