This resulted in a $50,000 scam.
Totally fucked situation. I was reading the other thread. It was well organized and planned at least that's how it looked to me. The escrow did not have anything to do here. If you send me a message and then another message from your account then another message from the same account I will obviously think it's you. I would not have any idea that your account got hacked and someone else will send messages from your account.
May be we can always add a signed message using either PGP or known bitcoin address. This way you have one more option to verify a message even if this come from an expected source. Like in MJ's case if there was a signed message using bitcoin address for every PM the sent to each others then verification could be stronger.
I was surprised to see an established escrow provider say to ship items directly to the buyer after payment
The sender can give a fake tracking ID or used tracking ID and the escrow would think it's real. Or even worse, the sender can send something else, may be a piece of brick and get a tracking ID for it. Send the tracking ID to the escrow and escrow will think the item was delivered LOL
