This is a pure scam site run by a guy named HABBA, he fakes being the escrow guy but once you give him money you can not get back on the site to defend yourself and he will act as the buyer who never gets his goods. Habba will say he did. I was able to get back on by tricking him going via Tor and saw all the post written for me that I didn't do, and must be the same with all the others.
I have reported them to the FBI, FTC and a few other warning sites for scams. This is a bad one, don't trust him and tell HABBA that his customers say he's a crook, he will ban you!
