PayPal is the only service where I was ever hacked. I had someone use my PayPal account to buy merchandise in Europe. Ever since then, I shut my account down and have not used it again. Every once in a while I get an email asking me to use it again and explaining how safe it is. I reply by telling them how I got hacked.
Interesting. My PayPal account also was hacked. Someone tried to use it to charge several thousand dollars of camera gear. I caught it in time to reverse the order before it was shipped. I rarely use PayPal now. Maybe I should simply close my account with them.
