Ummm in that thread it says you were blacklisted for a week.
@BACKD00R banned you. I assume you continued to trade/sell while you were blacklisted.
Generally that is a permanent ban. Your ban isn't permanent.
Confirmed with @Symmetrical that you were banned for trading while blacklisted. Be thankful your ban isn't permanent. Serve it out, and then come back and resolve any pending issues.
If you are found to be trading on this account, you will be permanently banned on both accounts.
Misunderstanding according to Symmetrical. Your ban has been lifted.
