It is a bummer on the unfollow webhook, but I am sure for performance reasons that isn’t planned. Right now, the only way that I am aware of to tell if folks unfollow is to hammer the follows endpoint and reconcile it against previously noted followers.
I am curious, Dallas, since IRC has followers-only-mode, if it would ever be possible to provide a follower=1 tag much like the subscriber=1 tag? I completely understand if this would be a performance drain, but just curious, because, if this was the case, then my bot would have almost no need to ever even pull the API endpoint or use the webhook.
Cheers
