Something like that is probably technically possible, but you'd need to do a bunch of work.
Plex Plugins can't provide media sources anymore, so you need to do the trick plex_debrid is doing where you add stub sources to the plex server library and serve the files from a virtual filesystem.
You might be able to re-use the plex_debrid code but use youtube-dl
instead of rclone
the mastodon spam that's mostly died down... we'll see how that ends up. we saw similar things where admins got told to turn on approvals for all new accounts... which isn't super scalable.
Anyway, Fediverse is finally important enough to send spam to, we'll see how well devs can make solutions for spam on a federated platform.
But yeah generally agree, there's no conspiracy here, it's just fighting spam is hard... and having an account with X amount of Karma is hard for a bot to pull off (without leaving a really obvious paper trail of bots upvoting each other)
