Facebook has estimated that 8.7 percent of the social network’s registered accounts are fake.
The company’s number suggests that 83.09 million accounts (of its 955 million user base) are either fakes or replicas.
Duplicate accounts (an account that a user maintains in addition to his or her principal account) may have represented approximately 4.8 percent of the worldwide MAUs (monthly active users) as of the end of June.
User-misclassified accounts may have represented approximately 2.4 percent of our worldwide MAUs, and undesirable accounts may have represented approximately 1.5 percent of our worldwide MAUs.
Facebook also said that it bans at least 20,000 accounts daily.
