There may be more than 83 million fake users on Facebook, the giant social network has revealed.
Duplicate accounts, people who have an account in addition to a principal account, make up 4.8 percent of the “fake” accounts, as of June 30, 2012.
There are also “user-misclassified accounts” (2.4 percent) — pet accounts or a personal profile for business — and “undesirable accounts” (1.5 percent) that are intended for spamming, etc.
Fake users are a huge concern to Facebook because it generates a majority of its revenue from advertising. BBC.com says Facebook is coming under increased scrutiny over the worth of its advertising model which promotes the gathering of “likes” from users.
