Twitch is okay for livestreaming, but not the safest option for documenting protests or sensitive law-enforcement encounters. Their moderation is aggressive and unpredictable - streams showing violence, blood, or law-enforcement clashes can get taken down instantly, and accounts can even be suspended.
If your goal is durable evidence, Twitch should be secondary. Multi-stream to YouTube, X, or decentralized platforms, and record locally at the same time. That’s how footage survives even if a platform decides to hit “delete.”
