eBay fraudsters mastered this. They would buy and sell bullshit items like old postcards that would be shippable via first class mail, then wait a few months for the auction listings to expire, than sell a fake laptop or camera.

I was almost defrauded like this but refused the shipment and was able to claw the money back via chargeback at the cost of my PayPal account. With about 15 minutes of searching I was able to find networks of these phony sellers building up eBay points and running these scams.
