We've all seen it: a huge international tournament or event is ending, and the channel hosting that event with 30,000-200,000 concurrent viewers ends their stream by raiding a small content creator with 30 or so concurrent viewers. While this is an amazing act of community support, it often completely inundates and overwhelms the raided channel's ability to moderate the stream.

A nice feature would be to allow the streamer (or maybe their mods) the ability to temporarily allow the raiding channel.

Otherwise, as an extension of the current 'knock' collaboration feature, a large raiding channel like this could use a hybrid raid-knock feature that, at least for a little while, if accepted by the raided streamer, allow for the chats to be merged (preserving both sets of moderation staff), so the raiding channel's moderation staff could help deal with any unruly actions by the people they're bringing over.

Tl;dr: 'give streamers the option to temporarily allow raiding channel staff to moderate during a major stream raid'
