"Impersonation

* For example, you may not:
- Impersonate a Twitch partner’s account
- Pose as a celebrity in a streamer’s chat
- Create a “waiting room” i.e. a stream with the title, tag, or description of being a “waiting room” for someone else's stream or channel content that contains no reaction or original content created by the channel owner"
