It's a bug. theymos already addressed that issue/bug on another thread:
After further investigation, this was in fact a bug. It looks like about 10% of payments made between March 3 and now were not credited. I put a notice at the top of the unproxyban and promote page so that people can email me and I'll sort it out for them.
Simply read and follow the second line:
Due to a bug, some payments made between March 3 and March 5 were not credited. Only if you ALREADY PAID and it was NOT CREDITED, email your username and the Bitcoin address to which you paid to mar18paybug@theymos.e4ward.com.
