I assume you were banned for selling Malwarebytes keys. Today several threads in a row related to selling Malwarebytes keys were deleted. And your ban followed immediately after the deletion. You were not the only one to get banned. Along with you two other users were banned, who were selling a similar product. They are dabsee and Windows | Office. Their threads have been deleted as well.

P.S. Again, this is just my guess. The real reason for the ban know who banned you.
