Idea: if you mod a community on a lemmy.somewhere you should be able to migrate it to lemmy.elsewhere which would include all post & comment links being forwarded and subbed users having their subscription updated to reflect the new location.
I’m aware this would be a way down the road as user account migration alone is still not great but it would be a great feature for the fediverse to have to avoid centralisation and mod/server admin wars.
But that’s not what this conversation is about.
It would be the mod/admin who moves a community to a new instance, and the users would migrate themselves to follow the community.
Neither functionality exists but I agree that users should not be moved automatically unless it’s part of an SSO scenario.
That’s not what I read anywhere but I agree with the way you worded it.
I might have made some of that up but thank you for catching the intent of it.
