Not to enrage the Bieber Nation or Beliebers or whatever Bieberian name tweens and post-tweens call themselves now, but it looks like a lot of the people who follow him on Twitter are fake. In fact, he has the highest number of fakeout Twitter followers out of the top 10 Twitter accounts. 16.7 million accounts are fake! 2.6 million are inactive! Those numbers are ridiculous.
Bieber has 17.8 million real followers (a lot! but certainly a lot different from his listed 37.2 million followers) which puts him in second place in Twitter popularity behind Lady Gaga, who has 19 million real followers. The fake stats were found by Statista using the Socialbakers tool which weeds out fake accounts by looking at their tweets to see if they include spamworthy words like "diet", "make money" and "work from home". It's not too surprising that all these popular stars have so many fake followers (Et tu, Barack?) because massive popularity is a magnet for spam leeches. From Statista.com
