I was not aware that TMI.js was a third party script, but even then, its namesake is Twitch’s own service, which begs the question of why Twitch would offer everything BUT follower notifications through TMI? I feel giving follower alerters the option to receive follower notifications as they come is a far better alternative than having thousands of streamers polling the API for 25-100 followers at a time when they really only need the latest ones. Imagine smaller streams needlessly polling the API for followers when there is a new follower every hour or two. Inefficient if you ask me.
