A confidence trick is an attempt to defraud a person or group by gaining their confidence. A confidence artist is an individual working alone or in concert with others who exploits characteristics of the human psyche such as greed, and the thought of trying to get something of value for nothing or for something far less valuable.
At the end of the day most of the scams are just US being stupid. I only have 200 or so posts but I have learned, by losing a shit ton of money, that I am not going to buy anything from someone who just appeared. There are a TON of high rep providers.
These Con artists arrive, make nice for a while, gain some iTraders, then drop a great deal. People jump on it because we are greedy and then find out it was a scam. If it looks like a duck and quacks like a duck, it is most likely bull shit
