"Stop these scammers from scamming again"
The forum doesn't stop scammers, nor could they even if they tried. This statement implicitly puts responsibility for the problem on others rather than himself. He then goes on to say how he is "done with this Bitcoin peer to peer exchange thing" as if the flaw is in the system or the forum rather than his own lax behavior. New users need to learn that the forum is not going to protect you and you need to do the due diligence to protect yourself. I am sorry if this harsh reality got your panties in a twist, but again if we are actually trying to help these people they need some "tough love" and not a changing of their pampers every time they do something dumb then blame everyone else. If he had spent 5 minutes reading thru the forum first this could have been prevented.
I only see him placing the main blame on the two vultures who easily gained his confidence and conned him, which is exactly where most of the blame belongs. I don't see him blaming the forum or "everybody". Also, I can understand the reluctance someone would have in participating in the direct peer to peer exchange thing when the result was getting ripped off. Perhaps he will get back up on the horse again when he comes up with a better strategy to prevent getting so easily duped. Also, I think the $1300.00 loss gave him enough "tough love." That's a rather pricey expense to pay for getting schooled in the college of hard knocks. I'm sure that your extra 2 cents of "tough love" are really not needed here.
Judging from his post and his action, he has not done research on people whom he is dealing with, did not check the reputation and do escrow, he hastily trade, for me it's a big amount but getting scammed the second time, the blame is on you, unless you did precaution on how to trade correctly.
The lesson to be learned with the second scam is that one should always be leery of people who offer you a sympathetic ear with their palm extended. Chances are they are just another creep who found an easy mark.
