Who is the escrow?
none, because OP already said if the seller doesn't want use escrow because that's just little amount (this is reason why the scammer doesn't want use escrow)
I 'm using an escrow but he says this is only a little amount , is not comparable with the price of his account .
If he can't get the money you lost, why he is the escrow? LOL.
same answer with above, both of them (OP and the seller) don't use any escrow
