TORONTO - Some Facebook users are learning a tough lesson about the importance of privacy settings.

A new website is exposing embarrassing Facebook messages posted by users, who probably don't realize their privacy settings are turned off.

The website FacebookSearch http://youropenbook.org/ includes posts with people brazenly admitting to playing hooky from work.

Others pull no punches in making fun of their bosses. And some are of a very personal nature, falling into the category of too much information.

The founders of the site say they have no malicious intentions. They simply hope to show naive Facebook users that there are very real consequences to not guarding their privacy online.
