Quickseller has done a lot more than pretend to be his own escrow to scam coins.

He also has a history of constant lying - to the point where you cannot trust anything he says anymore.

He also has extorted a few forum members when he pretended to be hurt about one of my comments.

He also pretended to be banned.

There is no doubt in my mind he has scammed many others using his dozens of alts. 

His trust rating should be lower, but he is an old user and a lot of DT members still protect him when they shouldn't.
