Privacy and social networking sites

Social networking sites like Twitter, Facebook, and LinkedIn offer ways to stay in touch with people you know. They make it easy to share photos, videos, status updates, and links. However, if you use social networking sites, you risk exposing the content you post to the wrong people.

The content you post on social networking sites is public by default. When you post photos, videos, personal information, or status updates, anyone can see them. You must change your privacy settings to restrict content from being publicly available. Chances are, not all of the content you post on Facebook should be public, and it is essential that you change your privacy settings accordingly.

Follow the guidelines below to enjoy the benefits of social networking while also maintaining your privacy and protection.


  • Consider the necessity of posting personal information on social networking sites. Is it necessary to post your phone number, address, or IM screen names?
  • Know that your content can be, and sometimes is, archived. For example, The Library of Congress archives all tweets from Twitter's inception in March 2006.
  • Investigate and use privacy options.
  • Don't post anything online that would make you feel uncomfortable around your family or employer.
  • Don't post pictures of people without their permission.
  • Don't post pictures or videos depicting illegal or dangerous activities.
  • Don't post copyrighted material.
