Not necessarily. If the goal is to attract people to Nostr streams that might work for long enough. Tbh I have no idea how Twitch plans to enforce this rule. My guess is what they don't want (and hence monitor) is streamers going live on Twitch and YouTube/TikTok/Kick at the same time. I don't see them going after zap.stream just yet (no offense @npub1v0lxxxxutpvrelsksy8cdhgfux9l6a42hsj2qzquu2zk7vc9qnkszrqj49 😆)

This rule sounds incredibly dumb and draconian
Twitch bans multi-streaming only if you're a signed streamer, as in you have a signed contact with them as a "partnered streamer".
If you're not signed, you can stream wherever you want and on as many platforms as you want simultaneously.
