What if uploaders locked up sats which serves the purpose of reducing spam because now the uploader has skin in the game and paying for the initial video hosting, then to watch the video it costs sats to fund the video hosting over time maybe you can charge periodically as the video goes so people can see if they like a video before they pay for all of it. Maybe the more popular videos give a portion of the sats to creators. I’m not sure video hosting in nostr is a great idea Just thoughts I had on your post.
