Just when you knew it was unsafe to get in the Facebook water comes another reason to watch your back.
Insurers, credit agencies, credit card companies, banks, etc monitor Facebook closely to determine your credit rating. Reportedly they've been doing it for a couple of years now. They search for phrases like bankrupt, job loss, slow down, and anything related to difficulty paying bills. It doesn't matter if your account is set up to be private, they can access info when from your friend's or family's accounts that are set up with more lax privacy settings.
