Sad times when you sell a default trusted account for peanuts. A few hundred dollars! It was always going to end up with the community being f'ed over for that small price.
You handed him the keys to escrow 5-10-15+ btc. That is a terrible thing to do to the community. There must be some good in you to not have scammed the escrowed funds which is not that much good because you let someone else do it instead.
Now he walks away with 10+btc and you get doxxed.
Possible fake sale.
