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.
Proper backup protocol raises HW requirements. But if you want to do something right, it’s just the cost of doing business. There’s the old saw, “If you don’t have time to do it right, when will you have time to do it again?” But there may not be an opportunity to do this one over.
I foresee moneyed interests working steadily, diligently, relentlessly (with paid labor!) to help this entire effort fail. The success of this concept represents the loss of inestimable billions to today’s dominant platforms. Those corporations will, as always, work hard toward their self interests.
