This was reported to me by another member, and I PM'ed grtthegreat asking him to delete the selling posts, as this is a situation much like the one with iluvbitcoins where I don't think the member is deserving of a neg in the face of a lot of other positive trust. I explained that I wasn't going to tag him but that other DT members might feel differently. In his last PM to me, grtthegreat said he was done accepting accounts as collateral and done with account sales.
I'll probably get shit for this either way, but I tried to make a fair call on this one and not repeat the mistake I made with iluvbitcoins. The account that got bought is another story, however. I'm going to have to wake up and drink coffee and reread this thread.
