Sorry to read that then but at least you've got the right attitude, I'm impressed by how you're able to easily remember that one bad experience shouldn't put you off interacting more with the rest of this amazing community so I respectfully tip you my hat.
If I were you, I'd try to contact PayPal nonetheless, perhaps repeated complaints (the victim from the other thread said he introduced one) against the same user could have an effect ?
Wishing you the best luck for the future ;)
