There have been some concerns expressed regarding the use of Facebook as a means of surveillance and data mining. Theories have been written about the possible misuse of Facebook and privacy proponents have criticised the site’s current privacy agreement. According to the policy, “We may use information about you that we collect from other sources, including but not limited to newspapers and Internet sources such as blogs, instant messaging services and other users of Facebook, to supplement your profile.” However, some features—such as AIM away-message harvesting and campus newspaper monitoring—have been dropped, even though the clause still remains in the policy as of November 26, 2008.
The possibility of data mining by private individuals unaffiliated with Facebook remains open, as evidenced by the fact that two MIT students were able to download, using an automated script, over 70,000 Facebook profiles from four schools (MIT, NYU, the University of Oklahoma, and Harvard) as part of a research project on Facebook privacy published on December 14, 2005.
