Xiaolius is a scammer. Same exact behavior as Peezr on Mastercoin trading thread, right down to claiming to issue refund which never comes through. At least in this case he has made very little compensation for the amount of time he has invested in developing the Xiaolius profile.
I think he does it for entertainment and the challenge as the money. He is clearly a sick individual.

What happened: Seller offered NXT for sale in NXT trading thread. He suggested escrow or break up into smaller transactions.
