Oh, I forgot... they could probably tell you which IP(s) accessed the account...

If the IP matches your IP range, then you know who logged in.

If the IP isn't in your IP range... thats another reason to suspect something.

(Of course, if you are using a proxy, that would mess everything up. Test results wouldn't be reliable.)

BTW: Good luck finding out any of this info... From what I've heard... Paypal isn't the most helpful service. They'll take your money, but when it comes to helping you... you have a better chance of getting a problem resolved from a Dell tech support agent.
