If you have a gambling site or MoneyPot app you want to sell, hit me up for a quick deal!
I think it would be very hard for you in making a transaction with other bitcoin users because you have a negative trust even myself would have a hard time in trusting you in my opinion.
But as far as I know he can use a trusted escrow and then there should not be any problem.
Have you bought any sites yet, OP? If yes, you can provide some info on that so people here would trust you more. Good luck with your buy anyway!
LOL he bought donutbit even OP didnt want to sell it to him. at the end he sold it to him cause it was just another user name. but he got paid. and as you said if he escrows all should be fine for the seller
