Ebay buyer sends $2500 to PayPal for a purportedly antique violin. After receiving the item, he claims fake and demands a refund from the company. PayPal say they'll refund after receiving proof that the instrument has been destroyed.
Even weirder, they apparently accepted the picture the buyer sent in, which could be of any other destroyed violin. So the vendor didn't get her money, nor her violin back, after what probably was a simple misunderstanding of the item's description on eBay.
I don't think I'll ever accept payment via PayPal.
