Twitch, please bring back the feature that removed someone from your followers list if they were banned from chat. This was so handy at slowing down harassers/bots, and I'm not sure why they went back on it.

Secondly, if it's possible, please implement a tool that will permanently kick someone off your channel page/redirect them to elsewhere. Maybe an error page that says "Sorry, this page doesn't exist", or a black screen over the stream and chat so it's no longer visible to the person who was banned.
