You can start an individual law suit if you want to but others have spoken to lawyers who won't touch it as paypal are doing exactly what is agreed in their legal user agreement.

You may spend out a few thousand more in legal fees than what paypal have held though.

But you can't do a class action law suit anymore as per link.
