I have to ask ... How exactly would this work?
After the wire is sent you can't go back and get it
Even with escrow the wire is already sent and unretreveable and this is a pretty large sum of money...
Because if they can prove beyond a doubt that the wire was sent to the details I provided then the escrow releases the money to them. If they genuinely did send me the money I would release it anyway, I'm not a scam artist.
Really, if anyone knew who I was on 2p2 I have never scammed in my history, I've done 100s (no exaggeration) of trades totaling millions and have vouches from the best in the game (wcg|rider, jungleman12, many more - PM if you want a list and know who these people are).
Additionally, it would be really stupid of me to accept money via these means because I have to provide my irl details so if I scammed then it would be pretty easy to file a police report... whereas this isn't the case with say western union.
