Just the other day there was a whole article on here about a guy who bought a house from a scammer and ended up being allowed to keep it because he bought it legally and was under the impression the scammer was the real owner. Nice of EVGA to put this warning out but it's not quite as simple as they make it out to be here, possession being 9/10ths of the law and all that. A person buying one of these at retail prices from a store would have no way of knowing that it was stolen, and someone buying one second hand at a reasonable price for the second hand item would likely also not be aware of its history. Of course buyers need to make sure that what they are buying is legit but that burden is not exhaustive, you don't have make more than a reasonable effort.
