Unfortunately somewhere down the line someone is going to get conned either by a regular poster or a relative newcomer. I think if we are all relatively cautious in our dealings and deal with issues swiftly and fairly as a group when problems do arise then we will be fine. There is no perfect system that I can see when it comes to things like this. Whether it be face to face in a shop or at a toy fair, or VIA internet auction sites or forums. There will always be an element of trust involved. It will always be like this as far as I can see.
