Well, the question is why do you want to get auto-followers to begin with? Nowadays, it's so easy to get tons of followers becuase of the software that's out there, that people and companies don't look at your followers list anymore as recognition of how important you are. You should definitely try to follow people who interest you personally (or your work), and there will be a much higher chance of you following them back.
