Probably because of fake followers. You can buy a few hundred thousand at a time on fiverr. They no longer 'sell followers' probably due to fiverr ToS changes, but they will 'promote your account' which I'm sure is the same thing. As a gag I once bought a million twitter followers for around $400. They decayed at about 5% per month until only a few thousand were left when I closed my twitter account. example: https://www.fiverr.com/search/gigs?utf8=%E2%9C%93&source=top-bar&locale=en&search_in=everywhere&query=twitter%20followers https://www.fiverr.com/search/gigs?utf8=%E2%9C%93&source=top...
