That proves absolutely nothing. Everything was transferred in the sale, meaning that the escrow could have been completed seamlessly.
That's a point i can't believe again. Who in their right mind would sell a forum account including wallet that maybe contains 10 bitcoins for 1 or 2 bitcoins? It's pathetic to believe that this could have happened. So stupid can nobody be. Especially not an escrow who is trained to sniff out potential scams.
No, beyond possible.
