Incase you missed the trick,this is an anonymous system and if you fall prey to scams, there is absolutely nothing anyone(admin or any user) can do about it,.in retrieving your lost money or tracing the scammer..
Before using an escrow(Trusted) service it has to be someone the both parties trust,and I really do not know how you'll accept such service without trust,ranks don't emit trust, the fact that one is a legendary or hero member doesn't mean he or she is a trusted member,you need to go through his or her trust ratings,and make sure he/she is a reputable member of this forum
Always make enquiries as a noob before engaging in such service,you claim you have proof, we'll love to see them, at most a DT would leave a red trust on the so called "Legendary" member,but sorry your bucks is gone.
I made a thread about trusted escrow service earlier today,i think it's been overlooked on the forum(Trusted escrow service) and I think more discussions should be held about it
