My biggest gripe, with ebay/Paypal, is when a scammer has their account suspended and the sellers who were affected aren't compensated. This happened to me with a US buyer, several years ago, who claimed they didn't receive the item. Up until this point, I never had a problem with any of my scores of US transactions, so sent it without tracking. After scanning through their feedback, I discovered that the buyer had scammed other sellers (they were leaving positive feedback but with scathing comments). However, ebay/Paypal still refunded the buyer, even after bringing the feedback history to their attention. Several months later, when the buyer's account was finally suspended, I got in contact with ebay and queried about being compensated. I never got a reply. My selling days, on ebay, are nearly over but, these days, I check the buyer's feedback history before posting the item.
