The reason the follower status is not integrated into VIP / Points systems is because it is a very
loose status.
People can follow and unfollow at any point in time. Keeping this list synced with twitch is much harder that it would seem.
Additionally,
twitch has recently put in restrictions that prevent us from checking the status of more than the past 1,600 followers. As such, any stream that has more than that number of follows will find that the follow status of users within DeepBot is not fully synced with Twitch.
Overall - I can only see problems and ways to exploit any system linking follower status to anything meaningful as it is so easy to follow and unfollow making working with such a system frustrating for the end users.
