Keep an eye on your accounts, friends.
Yesterday I noticed three transfers going FROM my checking account TO paypal, which is the opposite to how it's supposed to go. I had no PP transactions in those amounts, so I called PayPal, and it turns out three ladies I don't know had my checking account linked to their paypal accounts. Warning: Spoiler! (Click to show)
Luckily, they stole under $200, and I'll get it all back tomorrow at the bank. Bastards.
All a thief needs is a check in order to get account number and routing number. PayPal needs to make it possible to limit access to one's bank account to just one PP account.
