That's a very interesting find, koshgel.  It certainly explains why he said upthread that escrowing for yourself isn't a big deal.  It seems slightly less malevolent than the QS scheme because it appears that each time he was the one to pay escrow fees.  That said, I think you're right to ask about double standards here.

EDIT:
I think the fact that Quickseller finally fully demonstrated the volitility of his modus operandi to the observers in this thread probably also has a lot to do with his fate.  For a long time, QS' unrepentant ire was only fully unleashed on newbie accounts and those with no trading history.  Those who he saw as "above" him in some way were always treated with reverence.  As QS seemed to fully explode and unleash the bile on Vod just upthread, the calling of "asshole" and stating how he's above the rules and risks that others have to abide by, I think a lot of people who weren't really involved in his treatment of newbie accounts got to see the kind of personality we're dealing with here.
