Why did I get banned?

The last one a mod replied that it tells me why I got banned when I log in. But this is all that is said.

You have been banned for the following reason:
Ban evasion

Date the ban will be lifted: Never

If you feel that this ban was given in error, you may explain why you think so in the Dispute Forum without registering a new account, and a moderator or administrator will review your case and come to a final decision.

In fact. I never got banned.
