I remember this being big on ebay days.
How can retailers like Amazon/Ebay verify neither sellers nor buyers are not getting scammed? I cant think of any solution except intercept all packages and make sure the actual product is there.
One of my friends still sells on eBay and has buyers pulling scams regularly. He lists stuff on message boards and other sources first, and uses eBay as a last resort. Personally I haven't been a seller on eBay in close to a decade.
This isn't a solved problem but its certainly solvable because scammers should be pulling the trick repeatedly.
