Protecting Yourself on Social Networks
Last reviewed: 10-19-2019
Social networks are among the most popular websites on the Internet. Facebook has over a billion users, and Instagram and Twitter have hundreds of millions of users each. Social networks were generally built on the idea of sharing posts, photographs, and personal information. Now they have also become forums for organizing and speech. Any of these activities can rely on privacy and pseudonymity.

Thus, the following questions are important to consider when using social networks: How can I interact with these sites while protecting myself? My basic privacy? My identity? My contacts and associations? What information do I want keep private and who do I want to keep it private from?

Depending on your circumstances, you may need to protect yourself against the social network itself, against other users of the site, or both.
