I saw a story on slashdot recently that is particularly relevant given Facebook again being in the middle of a tempest regarding their ever-changing security settings, practices, and defaults.
“Two online projects will scan and edit Facebook privacy settings for maximum
protection: ReclaimPrivacy (reclaimprivacy.org) and SaveFace (untangle.com).
The article says: ‘Several new applications have launched this week that are
designed to easily reset a Facebook member’s privacy settings, following new
changes from the company that make a sizable chunk of profile content public
by default when it was once kept under lock and key.'”
Here are the utilities mentioned. The first seems to be more flexible, while the second easily locks down your FB. These work for now, subject to any changes that FB may make that accidentally or deliberately hamper them.
