Shock: Facebook Is Tracking You Even If You’re Not on Facebook
Facebook's problems just keep accumulating, drip by drip—or more like splash by splash. It’s now been discovered that Facebook not only collects and uses the personal data of its members but also collects the data of those who never signed up for Facebook.
So if you're one of those who blames Facebook users for allowing their personal data to be compromised, don't be so smug. Facebook may be sharing your personal data as well.
Daniel Kahn Gillmor, senior staff technologist at the ACLU, discovered that, although he never joined Facebook or any other social network, Facebook has a detailed profile on him.
Facebook obtains information from those not on Facebook in two different ways: from other Facebook users and by tracking people who visit other other sites on the web.
When people sign up for Facebook, they’re encouraged to upload their contacts to make it easier for Facebook to connect them with their friends. That allows Facebook to access personal contact information for people who never signed up for the platform or gave their permission to share their information. Facebook knows that these contacts are friends of the new Facebook user, and can start compiling additional details on these non-members.
