Act while the stream is still live.

Rules decide what happens: warn, end the stream, or ban after repeat violations. Target the risk, for example only new hosts or first-time callers.

See exactly what triggered the flag.

The review timeline shows the rule and the frame or caption behind each flag, with the user's history alongside. Nora, your moderation agent, handles the clear cases first.
