This is an alt account QS created in order to sell a DT account (he revealed it's identity because he couldn't resist doing a little sockpuppetry/trolling of me while using it).  If you look at the post history of this account (assuming QS doesn't immediately delete posts), it suggests that the DT account was sold.  I can't speak to what account it was or whether it remained on the DT list.  I'm guessing QS isn't going to tell but who knows, maybe someone else will.

This post is pretty entertaining because you can see QS doing his now signature move of discussing something with himself using multiple accounts.
