Give bots a non-paid sub role.
A lot of Twitch streamers, affiliates and partners alike, use services like Nightbot and Streamelements for automated services. They are bots and do not contribute financially to Twitch on their own. Twitch bots also periodically use emotes in certain automated tasks, and require a sub for them to use these, among other things. It would be nice to be able to give known bots a non-paid sub, -OR-, allow bots to use channel emotes and other sub-related services permissible by Twitch.
Just an idea. I mod for several channels. Partner channels periodically use their non-paid permanent subs on bots specifically for this purpose.
