I have no doubt that there are things that Ebay experts could teach us that would be a valuable lesson here. But I think for the most part, it's the old saying. "If it looks too good to be true..." Or wait...maybe the saying is "There's a sucker born every minute..."
I wonder if those who truly pass off fraud ever get prosecuted, or do they just get kicked off Ebay, only to pop up under another user name.
