To my knowledge PayPal is on a witch hunt to shut down as many affiliate marketers as possible. A guy named Anthony Aires got shutdown and he was a big seller on Warrior Forum. He just put out a product on JVZoo about how to prevent it from happening to you. No guarantees though. I don't have the link and I'm not an affiliate anyway. But I'm sure you can find it if you look around a bit. Hope that helps.
PayPal should have emailed you when they blocked your account.. So submit those documents and they will unlock your account. If you used fake details then forget it.
