I even put the most basic and common sense rules in my signature but it's as if people wanted to be scammed. I agree it's really hard to feel sorry for them.
This one is no different. If you actually read his negative feedback, it says: "After Creating 50 accounts. The Scammer doesn't want to pay. I see he already has scam history.", so he checked the trust feedback only after he was scammed. Now how retarded is that?
However I am against all the scamming sometimes I think that if people exhibit such an extraordinary degree of stupidity they actually should be scammed, those children just won't learn any other way.
