A word of advice. In the event that your PP account gets negative balance, you won't be able to remove any sort of information from the account let alone delete it, meaning they will be in possession of your bank account, credit card and address etc. Thus, they'll be able to withdraw the funds in order to balance out your negative credit from your credit card directly without your approval, I believe. However, they cannot touch your bank account.
Just wanted to let you know, seeing as there are many potential chargebackers on Sythe.
