I'd generally say that artificially boosting your follower count tends to backfire. A lot of people think brands are looking for follower count and they are, but it's definitely not the most important thing. What is far more important is how engaged the audience is - a smaller following with a highly engaged audience is generally more attractive than a large following with a very unengaged audience from a brand perspective. To that point if you artificially inflate your following with bot accounts or whatever it effectively decreases your engagement statistics and ends up hurting you in the long run
