State and Federal laws prohibite this.. They can only inquire about the account attached and no others..
My reply to you will be for this first point as our experiences differ.
The other is 2nd hand from a friend.
I didn't ask about any PayPal issues at my bank. A bank official approached me when in the bank and told me about the PayPal requests for bank information as per my accounts. She asked if i wanted PayPal to have access to this info as she thought it was odd. I told her that they were only to have access to my CC account info, this was the original information given to them when I opened the PP account in early 2004.
PayPal has gone through several lawsuits and I guess policy changes. Maybe policies have changed.
My friend of many years had the checking account frozen for several months. Funds weren't available to him. This was an account set up for PP. He was a buyer only and not a seller. The items purchased were generally knitting items for his wife and an occasional inexpensive camera for hobby use. He is a very tech savvy guy working in the industry. He said that he kept about $300 in the account.
I can't tell you any more than that. Our experiences differ vastly.
And, I would add that just because a policy isn't legal, it doesn't mean much to some who think they can get away with the policy, not being punished or punished lightly if caught. Again, my opinion.
