Xtreme is the type of game abuser that ruins things for the "normal" players and makes it harder for them to play the game the way it was intended to be played. Once someone who can do something about this gets wind of what's going on, the game is going to have to change drastically to stop the item scammers. Something like this could completely end the trading and selling of items among users and would force everyone to only buy directly through Steam. It's a shame actually.
