Hi fellow escrows. I would like to get advice on how to handle a potential risk that I experienced lately.
I had a trade worth 260€. Everything went normal, deal ended with the seller sending the goods and the buyer telling me to release the coins. Only shortly after I received a pm from the buyer that he never received anything. I answered, only to get the message that I was blocked for answering the buyer. Shortly after I saw a scam accusation thread.
Well, first accusation was that I was scammed by the buyer who sent a message including our quotes from an account looking similar to the buyers one. First fright was gone when I realized that the pm came from the exact same account that the buyer owns.
It turned out he never blocked me from receiving messages so the only explaination was that his account was hacked by the seller so that he can get his coins back.
Next thing was that the seller claimed that he was scammed by sending the digital money to another account the seller told me. So the possibility was there that the buyer faked it and let it look like he was getting scammed. So that he had received coins and digital money.
At the end the story of the seller did not sound perfect and finally he was being revealed as the scammer.
Anyway the risk was there that the buyer would have faked it.
Third theory was that a third party was involved though this would have needed the other account being hacked too. So unlikely.
For information here the accusation thread:

https://bitcointalk.org/index.php?topic=1389494.new#newIt's the first time I hear of something like that where a hacker did not instantly change the password.
Now my question. How can an escrow prevent this?
Well, normally I would think that the trading partner would have to be cautious and that the escrow would have to assume that the trading partner was not hacked. But it seems there were voices like "so what will you do to prevent this?".
Well, I don't know. Some suggested that I demand a signed message when the seller sends me the address he wants the coins released to as well as the buyer sends one with his message that I can release the coins. Though surely that will scare away users. Even suggesting it... I know that it is a hassle only to start that topic, even with shorena's link on how to do it. Everyone who tried to explain signatures know that it can take ages.
Others claimed only to release coins when the escrow receives a screenshot of the payment. Well, that might have helped in this case, since I doubt the hacker sent anything at all, though I would not know if the screenshot is faked and investigating this surely would take time too.
And asking the trading partners to change their password because they might have been hacked sounds way too far fetched too.
So does anyone has an idea what an escrow potentially could do there? I mean it would have to be done in each trade only on the assumption that a trading partner could have been hacked.
