This. I was defrauded to the tune of $3,500 (run of the mill stolen Paypal account bought a top of the line iMac from me on eBay) and after discovering to my horror that both eBay and Paypal sidestep all fraud for protection... I called the FBI, police, etc.

They listened politely until I said how much it was worth -- one of my favorite quotes was "If you added a zero to the end, we'd knock down their door at 6AM tomorrow. For $3,500 it's simply not worth our time."
