The 2010 documentary catfish, and subsequent mtv series, offers an interesting look behind the curtain at the type of people who create fake facebook profiles. It covers a wide variety of reasons for creating them spanning from people who suffer from low self-esteem and confidence issues to not being able to reveal that they are homo-sexual out of fear of their friends and family finding out, just out of pure malice or even in one case creating a fake account story to get the show to pay for flights so they could finally meet face to face. Its crazy some of the lengths people go to keep up the charade and how much evidence certain people will ignore to keep the idea that the person is real alive.
