Now, each server has its own administrators, and those administrators are accountable for ensuring their server stays within the law in the territory where the server resides. This does indeed become a problem if servers in multiple countries are sharing a common media server.

That doesn’t invalidate the idea at all, but it adds some constraints. One approach is for servers sharing a media server to share the same moderation policy too, and that moderation policy should forbid anything that’s illegal in any of the countries where servers reside. Probably a better approach is that all servers can fallback to storing content locally. So when one server reports to the media server that an item is unacceptable, all other servers are notified that if they want that content they should cache it locally, and then it’s deleted.

It’s interesting to compare this to Bluesky’s Relay server, which does a similar job and has similar issues. But with Bluesky, everything must go through the Relay. This means Relays must be huge, and only large territories could afford to run them. In practice, that leaves everyone stuck with America’s censorship policies. This media server idea is much more flexible.
