"How do people make thousands of followers in only a couple of months? "
Let me answer this question. Once an Asian signs up on Steemit, he/she thinks of ways through which they can earn money asap. So in order to achieve this goal, they start playing "F4F" means follow for follow game. You follow other's person and that person will follow you. So that's how you make huge following in just a month or two. I will definitely show you some examples whenever I come across such account next time.

And I agree to this "I gauge interest based off comments and interaction."
