I agree with you. I was getting excited when I started to see my follower count grow and grow. Then I got looking at the accounts and realized, they aren't that old and they have very little SP and Rep. There is no way they are upvoting any of the content I am putting up, so I am not sure why they are following me. I also have those accounts that follow and unfollow me multiple times a day. I am not sure what is up with those, but it is kind of annoying!
