How Secure is My Facebook Information?
Spiderowych found some private Facebook information online, and asked the Web Browsing and Email forum if the social network is safe.
I use Facebook, but I wouldn't post my credit card number there--or anything really embarrassing. You have to be careful about what information you give it and with whom you allow it to share that information.
If you've switched to Facebook's new Timeline user interface (and you may soon have no choice), you can control who can access your information through that. Otherwise, you must go to your profile. Assuming you're logged into Facebook, you can get to your profile via the URL www.facebook.com/editprofile.php.
To the right of almost every item on your profile, as well as every comment you post on your wall, you'll find a small, black icon called the audience selector. It's a pull-down menu from which you can control who can see that particular piece of information. You can restrict it to friends, friends of friends, a custom list, or make it public.
But be warned: If you comment on a friend's blog, you lose the ability to control who will see that comment. That's up to the friend who originally posted it.
You might also want to go over additional privacy settings. Click the down arrow next to the word Home in the upper-right corner of the browser window and select Privacy Settings and examine what you find.
I'm just hitting the basics here. Facebook privacy can be frighteningly scary. You might want to check out the service's privacy information page. And for issues involving the new Timeline interface, see Prep for Facebook's Timeline Layout: 6 Must-Do Privacy Tweaks.
And if you're worried about who else Facebook might be sharing your information with--you're not being paranoid; you're being reasonable. See It's time to regulate Facebook.
