And don't link your bank account to your PayPal account.
Some folks don't seem to have any problems until they do.
Their agreement says they can go into your account and take any money they want at any time without notice or permission.
It's happened to me and others I know. I had to close those accounts to stop them. If you are a seller that's not as easy to circumvent, but use a dedicated account just for PayPal disbursements and set it up to transfer money out soon after it arrives.
The other problem is that it takes at least a minimum of financial integrity to have a credit card in the US but any US or foreign scum bag can open a PayPal account and you can't easily determine their motives.
