Scammer tag or not, the lesson should be that someone better have a handful of good transactions before you consider trading before they can even be considered reputable. Otherwise, escrow is always a safe move.
That is the scam these two were trying to pull - they were trying to build up a reputation through dishonesty.
I'm guessing the mods will not consider this a scam, this guy's nonsense was immediately identified and he wasn't able to use it to fool anyone. I'm sure he'll create a new account and try again. If not, there are apparently enough of us who are bored enough to link back to this kind of shenanigans when they try to trap a real person.
