The reality is you will only get followers if lots of people like your posts and give them upvotes. For that to work you need to write a large number of posts and the subject matter has to be interesting. People won't vote for boring stuff. If you write interesting stuff then they will follow you and read your other posts. Then your score will increase and follwers will start to appear..

If you are downvoted your score will decrease. Even if you write alot, it will still take time to increase your score.
