It's only for the FL users (or any other easy setup&forget tools because it doesnt worth to do manual works on it). Setup 10-15 (pref. hot fake girl) accs, upload 5-15 pics on each acc (make sure to use the same girl on one acc). On bio writte something like "Hello, I'm admin at @main.page" or "hello, follow @main.page I'm admin there" or anything similar. Then leave the accs to follow only...you wont get 1m followers with this method, but will definelly get you some extra followers.
