"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.
But it is needed, unfortunately because people like you only focus on the scammers. I would compare it to incidents of rape. People LOVE getting all bent out of shape about "victim blaming", and while the perpetrator obviously holds guilt, the victim also has agency and needs to understand that certain behaviors put them at greater risk. Walking around in a dark alley in a city center in the middle of the night for example, while one has every right to do, is still risky behavior. We need to be teaching people how to avoid these dark alleys, not just decrying the evil deeds of the evil people who will always be there. Teach people how not to be victims, don't just give them a hug and send them back into that dark alley.
