Searching lemmyverse.net yields the following:
None of the communities are actively moderated, and only .world has activity in the past month.
Is this a case where consolidation towards .world is permissible, or would it be wiser to consolidate towards one of the smaller instances?
IMO if world is the only one with activity, it would make sense to support that particular community.
In that case, we should probably consider finding an active moderator for it.
Consider yourself hired.
