I agree that the earlier messages state it was to be shipped but, I am not sure what he can do if he received a pm from both buyer and seller that the coins would be hand delivered and then another set from both that the coins had been transferred in person and to release funds - what else can he do but release funds?
I would not have agreed to escrow a transaction that involved in person delivery. What if for example, the OPs account had not been hacked, and there was simply a dispute as to if the physical coin was actually delivered? There would be no way to resolve the dispute as it would be one persons word against the others.
Notwithstanding the above, if the terms of the trade changed, I think it would be prudent to delay the release of the money. This would allow for the buyer to flag something as being wrong.
I dont argue against your points.
I just dont see what alternative minerjones could have had if both buyer and seller appeared to agree to an in person exchange and then both parties appeared to express satisfaction with the deal.
how can you delay funds transfer if there has not been any notification that the account was compromised and no indication of it either?
