Good infographic. The question I have is what are they going to do with all the fake accounts? Remove the fake accounts and you will be shocked at the number of real followers, let's say, both Obama and Trump have. I use Twitter extensively and try to ignore the issue, but it's such a nuisance because you never really know if who you are following and who is following you are real users.
