However PayPal have a long sad history of siding with the buyer even when presented with overwhelming amounts of contradictory evidence to the scam buyers nonsense.
Been there, fought them, got a credit ding for my troubles but at least I kept my money( twas in the days before they had rights to just raid your bank account for any perceived deficit).
Unfortunately a lot of buyers prefer PayPal for the protection they see it gives them.
And as gentlemen become less prevalent in the world, the worse it will get for sellers.
