Certain ones, like music trackers, can still be interviewed into. Once you get into an initial tracker and establish yourself, it becomes easier to find / get into new ones via forum invites. It's a long road but barring a time machine it's the easiest way.
I dunno, maybe I just had crappy indexers but usenet was always more miss than hit for me. Maybe it's superior to public torrents but private trackers are the gold standard.
I wouldn't do a mailing list these days, but as someone who spent the early part of my career interacting with devs that preferred this method, it's actually pretty ergonomic by a 2005 standard. A message thread aware, text based email client that can turn messages into patches in a keystroke makes it actually pretty comparable to modern code review...
I think it's hard for younger devs to get this because they're used to email being stuck in a crappy, unthreaded browser interface or Outlook etc. (which are terrible for mailing lists) and most collaboration taking place in code review and chat platforms like Teams/Slack but for decades before these were feasible, email was the way...
Sorry, why would Jellyfin be different from Plex for exposing to the Internet? Dynamic DNS service / static IP and router port forwarding just like any other self hosted thing. It requires a user/pass to login as usual. VPN is nice but not required.
Wikipedia says from Portuguese, through Persian, back to Sanskrit, being the grand daddy of English, calling it "cina", and/or it has to do with Qin Dynasty that unified China.
Probably better than whatever bullshit they would have gotten from Zhongguo if "Peking" was as good as they could do with "Beijing"
