More Facebook users are hiding their friends to protect themselves

Far fewer Facebook users are making their Friends lists public, which reduces how much third parties can learn about them


Facebook users have become dramatically more protective of not just revealing who they are, but also who they know. Significantly fewer Facebook users make their Friends list public now compared to just a couple of years ago. The trend is driven by the increased attention Facebook has received since 2010 over its privacy policies, dramatic site changes, and increased awareness that third parties can learn a lot about a person by who he or she is connected with on a social networking site, according to researchers at the Polytechnic Institute of New York University.

Although the study focused solely on Facebook -- more specifically, Facebook users in New York -- the findings likely point to a growing trend of users becoming increasingly concerned about how companies are collecting and using their personal data. Google, for example, has received plenty of attention of late for its changes to its privacy policies, as well as the latest revelation that it's forcing cookies on Safari users.

For the study, the research team crawled the public profile pages of 1.4 million Facebook users in New York City in March 2010 and June 2011 to determine changes to what information users made viewable on their public pages. The most significant change: In March 2010, 82.7 percent of users had their Friends lists viewable to the public. By June, the number decreased to 47.4 percent.
