PayPal wants me to “add a bank account”, another funding source. Credit card isn't working. Why?
Visit paypalblows.org to find out more reasons. PayPal wants your bank account info on file before they allow you to take payment. So setup a bank account strictly for this service, and if they give you trouble or suspend your account, simply never use them again and tell others of your experience.  I think the only reason why PayPal wants a bank account is so they can dip into it and take chargeback money.
