The moderation problem wouldn't have been hard to solve on USENET, it's just that nobody wanted to do it. It could work exactly like moderation does on Mastodon, where each admin is responsible for the content on their server(s). There isn't a technical reason why you couldn't do that, and even give individuals moderation rights on specific lists. Of course, this only affects your particular news server, but it lets the white supremacist post their insane ramblings over on Giganews, while you and I read less toxic version of the thread over on Cozy News. If you don't like the moderation on your server, go find another one.

> that's why peer-to-peer filesharing died

p2p file sharing is still huge, though. Most people just put their seedboxes behind a VPN to avoid getting DMCA notices.
