In a 10-Q filing, Facebook acknowledged that a total of 8.7% — or 83 million — accounts on the network are bogus. Of that 8.7%, 4.8% are duplicate accounts, 2.4% are user-misclassified accounts and 1.5% are “undesirable” accounts, a.k.a. spam.
The figure is a bit higher than the company’s previous estimates. In a March filing, Facebook claimed about 5% to 6% of its accounts — or 40.3 million to 50.7 million — were fake. The company also says it bans at least 20,000 accounts daily and estimates about 600,000 accounts per day are compromised.
