Interesting outcome... potentially

To Add. I have performed a similar action when I returned what Kruanic attempted to scam. The question of morality is interesting though. I feel KingOfSports shouldn't get what is owed until I get what I am owed, that, however, is up to TomatoCage and I would find it a difficult position.
Tomatocage put himself in this position when he decided to escrow it. He should pay you the amount.
The purchased account, the OP and Tomatocage (if he pays the seller) should all get negative trust as they helped a confirmed scammer profit.
