This is a big problem. It creates the illusion that /c/cats on one particular instance is the real /c/cats.

This is the root of re-centralization and it must be pulled out.

      • That’s besides the point. Of course it’s always possible to create new communities on new instances, and import posts from various sources, but the original community would be still gone.

        If an instance is shut down or becomes unusable for a long time there is no way to automatically migrate users to a new instance. Additionally, there is also no guarantee that all users will move to the same alternative instance. This can also cause unnecessary conflict around which alternative instance becomes the “legitimate” successor.
