Even with such high interest on their money market accounts, I am scared keeping a lot of money in my PayPal balance. First of all, they acknowledge that your money is not protected by the FDIC. Second of all, I've heard too many horror stories about PayPal freezing people's accounts.
I think you're visiting the secure site (https:) as opposed to the standard http://www.paypal.com. Secure shows 0/10 while standard shows 9/10. Maybe you logged out and were directed to the secure site and saw the PR?
