2.2 billion isn't the total number of accounts, it's the number of "monthly active users"--and Facebook would probably be in much hotter water than they are now if they cooked the books on that number.
This don't change my comment still many of them are fakes. I know people who have 5-6 accounts active at one time playing different games with 500+ friends on it. Many of those "friends" also are fakes, some even with the same profile picture of "real person" with fake data but I have nothing against FB, every medium is abused.
It's just interesting that not a single research was done on this topic that I know about. :)
Game limits, not wanting to share private account with some random folks used in games or for commercial purposes aka selling account later on and I can tell that this business is booming! :)
I've heard that you count as a monthly active user if you sign into something else using your FB account. If true that would inflate the number quite a bit
