I sold a lot of camera equipment on ebay and that's tagged as a potentially fraudulent item so they would always hold onto the customer's money regardless of my 100% positive feedback. So I'd sell the good, paypal would tell me the money was received but would hold onto it & tell me to ship. I'd ship and paypal wouldn't release the money until the customer gave positive feedback. If they were slow at giving feedback, or just didn't bother, I'd have to either wait another 2 weeks or convince paypal that the goods were signed for by the customer (which is much easier to do if you are a U.S. vendor). Overall it is a brutal system.
