Facebook is the worlds largest social network, which is approaching 1 billion users and currently stands at 955 million registered accounts, although it would appear that not all those accounts are real.
Facebook recently revealed that around 8.7 percent of their total accounts are fake, this is made up of duplicate profiles which makeup around 4.8 percent of all accounts.
They also said that 2.4 percent of accounts ate user misclassified accounts which include personal profiles for business or pets, and around 1.5 percent of users are described by Facebook as undesirable, we presume they mean that those 1.5 percent are spammers.
