This is an idea we’ve discussed internally on a few occasions. I can’t make any current commitment to timeline because we have a few things we have to do first, but we would like to provide this feature.

You have a lot of different suggestions here, the latter of which have not been implemented so I will leave the topic open, but I wanted to let the thread know that we have recently released the ability to remove followers from your list by Blocking them.

You can see how to Block a user here: https://help.twitch.tv/s/article/how-to-manage-harassment-in-chat#BlockWhispersandMessagesfromStrangers

Additionally, you can see your channel Banned Chatters in your Moderation Preferences in the Dashboard

Setting this to a partial release status as the majority of ads on web and TV apps should now have normalized sound. We are still continuing the work on this and will update the status again when it is fully complete!
