It's not about getting followers. It's about interacting with people and spending your time in the environment you like.
You're wasting your time with this follow for follow nonsense.
I'd recommend you to unfollow everyone you don't know and leave only people you actually enjoy reading. Start communicating more on the platform.
Also, write well-thought articles. And after a while, you will be surprised by gaining lots of followers.
It's not hard to do well on steemit. You just have to be patient and genuine.
