It's worth noting that some streamers already have systems in place to allow users to moderate without having the moderator badge by eg. letting moderators operate by whispering moderation actions to a bot (while not currently having the mod status or appearing in the mods list).

Implementing this officially however would provide some important benefits:
1. Moderators will be able to act faster. Using their normal moderator commands rather than whispering a bot or using a third party site is a significant speed-up.
2. The streamer would no longer have to manually merge the Twitch moderation logs with the bot's moderation logs.
3. Provide Twitch themselves with valuable data about "anonymous" moderation. Perhaps this method of moderation is far more common than current data makes it out to be?
