It's not this forums fault, it's the individual scammers fault! Every forum on the web has members who have been scammed. Every transaction where you never meet the seller face to face and wire them money without parts already being in hand carries inherent risk. You just have to hope the person you are dealing with has honesty & integrity. If they don't, well...obviously I don't need to tell you what happens next! But, if you have to be in this sport there's hardly any other way to do business, depending on where you live.
