It looks like they already have possibly scammed some others users before:

A minor lesson to op: Ignore user ranks. Anyone can buy an account on Bitcointalk of any rank. You should be looking at trust ratings. Deal without escrow (if you must or want to) only with users that have a high trust rating and have conducted a decent number of trades. Anyhow, I've left them a negative rating.
