What part is illegal? Are they sharing files on that instance and your instance re-hosts it?

From my understanding, discussions are legal, guides are legal, tips are legal, but actual files (aka “copyrighted content”) is illegal. There are no files shared there, links at maximum, but institutions should be after those content-sharing websites, not forums.

I am against this decision and I am happy that I am not part of admins team.

Missing at least these:

1. Load balancers/Reverse peoxies - Caddy, Traefik.
2. Missing DNS server “blocky” which I find way better than Pi-Hole.

Nice list, but could have more. :)
