Link communies.
When two communies are linked they act like one with multiple names distributed on multiple instances.
This would solve the dublicate communities on different instance problem.
The moderators of each community are primarily responsible for their posts and keep an eye on the moderation by the other community. If one side is unhappy with the moderation of the other, they can cut the link and vice versa.
Administrators act as if the others community’s post are part of the community on their instance too. If there are weird posts, the community gets banned etc.
