I was one the buyers.. I remember this post:
https://bitcointalk.org/index.php?topic=1360660.msg14237762#msg14237762That's how I got my initial amount in the seed address I generated.
I was looking for the original seed listing to subtract the amount from myself but as far as I could tell the original post was edited so it contained all the new addresses with the new credited amounts.
Cfb what if you add up all those addresses in his post that you credited to (it totals: (359k old notation) 997851629000 iotas [edited - miscalulated before]) and subtract that from the original seed addresses list to determine which account is his.
Edit: as you may be busy working on the new version if you still have the original snapshot list you can post that with the newer one and we can all check and confirm the address to freeze.
