The statement about social networking sites that is false is:

Your personal information is protected from identity theft.

Explanation:

Unfortunately, be it consciously or unconsciously, no one is truly protected from having their personal information stolen. In 2012, for example, more than 12 million people were victims of identity theft. Even if a person chooses to not expose themselves too much, their e-mail addresses, names, and passwords can all be stolen. Hackers sometimes use employees of big companies to infect those companies' systems with malware. Other times, they use apps that require access to the person's information before being installed. Therefore, no matter how hard we try to keep our lives to ourselves, as long as we use social networking sites and apps, we are susceptible to being victims of identity theft.

I'm assuming they mean background information on digital photography.
