Why is 70% of Obamas Twitter followers Fake non-existing people?

Is that supposed to make him look popular to fool people? This man is very sick in the head.
He makes up a imaginary white girl he "dated" in his book, now he makes up more than half his tweet followers?

Does he have bi-polar?

[Chewy Ivan 2]

He doesn't. The people conducting that survey defined "fake user" as accounts that follow a lot more people than have following them, which sounds like most real Twitter users to me.

Do you actually believe that Obama manages his account in this regard; that he makes fake accounts to "follow" himself? I am not saying that there aren't fake accounts, what I'm saying is that, I doubt he personally makes the accounts.

I've seen a lot of celebrities and politicians as well as a lot of companies gain twitter followers throw social media exchange website but also buying huge numbers of fake twitter followers to increase their popularity.

And believe me it helps a lot, especially for business, having people thinking your company is very popular is the best thing to do.
