But the system is easily gamed. The seller can send an empty box, and provide a tracking number to the escrow company to "prove" that they sent the item and then it is the seller's word against the buyers word about what was in the box.
That would not have fooled Bitmit's Escrow system. They made individual inquiries in every case, AFAIK. A tracking number is $2 and proves nothing.
In the case of starsoccer9, it absolutely did fool the "system" (which used to say that an empty unboxing video was sufficient proof of seller fraud). Bitmit attempted to revise history and claim this was never their policy, and effectively said that the tracking number alone was more proof that the item was delivered, than the unboxing video with the label still on, showing the seller & buyers' name/address, and tracking #, tape being cut away, revealing an empty box.
Shortly after, the site starts shutting down.
Scammit.
I think everyone should take video of them packaging the item, and then SEALING it with serialized security tape, then LOOKING CLOSELY at the security tape, to make clear it's serial number on video, and then handing it off to a USPS employee, and FILMING them weigh it and paying for it, and continuing to film the employee take the package to the back of the building where the other packages ready to be shipped are located.
Problem solved.
