Facebook has a total of 83 million accounts on the website which are bogus. It accounts for 8.7% of the total users, of that 8.7%, 4.8% are duplicate accounts, 2.4% are user-misclassified accounts and 1.5% are “undesirable” accounts or simply put –  spam. This was revealed through Facebook’s form 10-Q filing with the US SEC for the quarterly period that ended last June 30, 2012.

The number of fake Facebook profiles seems to be  increasing, in a March filing, Facebook claimed about 5% to 6% of its accounts — or 40.3 million to 50.7 million — were fake.

“We estimate that “duplicate” accounts (an account that a user maintains in addition to his or her principal account) may have represented approximately 4.8% of our worldwide MAUs as of June 30, 2012. We also seek to identify “false” accounts, which we divide into two categories: (1) user-misclassified accounts, where users have created personal profiles for a business, organization, or non-human entity such as a pet (such entities are permitted on Facebook using a Page rather than a personal profile under our terms of service); and (2) undesirable accounts, which represent user profiles that we determine are intended to be used for purposes that violate our terms of service, such as spamming.” said the filing.
