According to Facebook CEO Mark Zuckerberg, the company’s unofficial mission is to make “the world more open and connected.” But there are limits to how open you should be on Facebook and while you might enjoy sharing photos and status updates, there are some pieces of information you would do well never to share.

Who’s watching your moves on Facebook? Employers, stalkers, federal agents, and even insurance companies have been known to scan Facebook profiles for information. Just as troubling are reports of Facebook account hackers, who put users at risk for identity fraud. Even if you safeguard personal information with a “Friends Only” setting, there is a chance you’ve friended someone whom you barely know or have never met.
