EDIT: The ´scammer´ has been posted on that thread mentioned in OP about scamming many members already. 3 posts already acussing him. There's no sufficient proof for this but still, trade with caution.

His password was also recently changed, either hacker or bought account. Maybe its just the owner scamming, that we can not know.
According to amazonseller, he's been using his main account as an escrow to scam other members.
