Facebook is admitting in a recent filing that it believes that nearly a tenth of its users are fake. The company says that 8.7% of its 933 million users are not real people. Also, duplicate profiles, those of people who already have an account on Facebook, make up 4.8% of its membership.
The numbers are critical for Facebook during a difficult financial time for the company. Even though the firm is earning hundreds of millions of dollars, the fake profiles add to the increasing concern that its advertising methods are ineffective.
