The ban you appealed ( http://www.pbbans.com/mbi-viewban-1bc171ab-vb42066.html ) does not even appear to be your ban at all. I'm not sure how anyone even came up with that being you either. From what I can find, you have 1 bf2142 GUID that is clean and is not associated in any way with the banned GUID.
If you could, join a PB enabled server, bring down the console with ~ and type pb_myguid. Write down the last 8 characters and post it here.
