Nice article, man!!
There are many bot farmers, you can actually buy a Youtube or instagram visitors for a low price. In my country, if you want 2.000 followers on instagram, you will pay around of 200 dollars, and behold!! You're famous!!
Recently I saw an experimental documentary showing how to become a successful instagramer in a week. They just picked a girl (an actress), borrow some clothes from fashion shops, dress up the girl, take some pictures of her and buy 5.000 bots-instagram followers. In less than a month she was ask to go for free to some nice restaurants, and she was invited to any social-fashion event you can imagine. The girl acted as if her account was real, and now she's actually getting huge profits from it.
Many, many middle-famous people begin this way, for the social media is programmed to give them more views based on their followers, and to scale up is easier if you make a tiny investment.
It is amazing how important bots has become. But it is amazing this kind of stuff has any probability of survival in a Forum like this one. Instagram is one thing, but here? Really?
That's the reason why I think we need as soon as possible a report button in each profile section...
