Yes, as I mentioned in my other post, people often buy fake bot followers for twitter and the same is now widely available for Instagram.

Apparently, it looks like you can get some real followers now as well or that’s what is advertised.
It’s not uncommon to see tens of thousands of followers on Twitter or any other social networking platform really and very often it begs the question how do these people get these followers. The reality is that many of these followers are not real, just fake created accounts that follow these people. Even the large media platforms like Facebook & Twitter admit that there are millions of fake accounts on the platforms that they are actively trying to fight. To see whether the followers are real or not check the interaction rate. For instance if you see 10K likes on facebook & very small amount of people talking about the page then you’ve got your answer. Real followers like, comment, re-tweet etc.
