Earlier quoted context omitted.
>It’s a very unethical practice because it ends up hitting businesses at the worst possible time, when the termination or suspension causes a huge financial hit. You forgot the part where Paypal get to keep your money when they close your account. And it's not like they only keep it temporarily in case of lawsuits/chargebacks, they just keep it forever. I still can't believe that crap is legal.
Are you saying you should empty your account constantly (nightly?) in case paypal gets shut down your account, for unknown and un-communicated reasons?
This doesn't really help. When you link your bank account with PayPal the link is 2 way. I.e. PayPal can, without any input from you, transfer money out of your account. They can even do that if the account is empty. Your bank will almost certainly allow an overdraft on your account and you're still liable for the amount + overdraft fees.
I had some issues with PayPal about a year ago and a senior rep at my bank talked me through these details.
With my bank, it wasn't even possible to turn off the overdraft feature.
Bottom line is, PayPal almost always wins.
