Quote from crackedback:
If you want to save yourself headaches with Paypal. Open a free checking account and keep no money in it or a very small amount. That way if you get a screw job buyer trying to backcharge there isn't anything to take. Close that account and open a new one. Wash, rinse, repeat.
WRONG.....PayPal can not withdraw funds from your bank account, if there is a chargeback only funds in the PayPal account might be affected. So it's best to transfer funds from PayPal to your bank account, no need to open up another bank account.
The CC companies don't like chargebacks, the scammers will loose their card.
