Briefly explain the trade: Well I did some research into his supposed vouches for diablo 3 beta keys and it seemed legit (one of them was even posting diablo3 beta screenshots on youtube) so I thought all was well and went ahead with the trade and sent $60 via paypal.
How they scammed: It's been over a day since I sent payment and he blocked me on MSN and another MSN as well. He's been active on this forum and has gotten my PM regarding this transaction but no response.
Proof that you were not talking to an impostor: E-mail matched on MSN..his supposed vouches here: http://sythe.org/showthread.php?p=10172626#post10172626
