Facebook users are being reminded to protect themselves. A new Consumer Reports study finds that 13 million American Facebook users have never touched their privacy settings.
About 28 percent say they've shared their wall posts with people outside their friend group. Experts say if you've never changed your default privacy settings, chances are you've probably shared more about yourself than you want.
And privacy problems are on the rise. 11 percent of households using Facbeook say they had a bad experience in the last year from being harassed by someone using their log in.
