I set up a fake Facebook profile 10 years ago, because I needed a profile with no friends that I could use for testing some stuff at work. It is still alive and kicking; Facebook keeps sending it emails suggesting friends.
We can spend all day arguing anecdotes. As a counterpoint, I've never used Facebook, but once tried setting up an account to participate in a group event organized by some friends - by the next day, before I could even use the account, Facebook had locked my account, and wanted a photo of my ID to let me access the account. Needless to say, I abandoned the account.
