You can now continue following people who follow you back. Gold Nitro will not auto-unfollow users who follow you back when you check the “Keep Follow Backs” option on your dashboard.
This can help you retain followers: people we auto follow are less likely to unfollow you if you continue following them. Though, remember to keep your overall “Following” number low.
You can turn on “Keep Follow Backs” in the Gold Nitro dashboard under Unfollows.
