I'm not an eBay fan and believe comments about they're not being that active in anti-fraud are generally true. They have, however, and on two separate occasions, removed listings when I notified them of obvious fraud. They confirmed in both cases and removed the listing. One was for a 200-400 Nikkor lens, rare and expensive, where the guy claimed to have five to sell. The other was a listing for a Nikon F3HP for a "buy it now" price that was exceptionally low for the condition stated and the photos provided. As earlier stated you have to use a little common sense and check out sellers. With all the millions of advs. placed you'll be foolish to trust eBay to catch even a small part of them .... even if they wanted to.
