Well I'm going on Vacation for week if your PayPal account still has claims on it when I get back.
I'm going to do a John Doe Lawsuit(To get all your Info from PayPal)
For $600 + Damages (NSF fee's + Late Fee's)
and get a judgement on the PayPal Account while the money is still in there.
If you're already getting charged excessive NSF fees and late fees over $600, good luck finding a lawyer...
Though, $600 would still fit in small claims, and you could represent yourself...
