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.
All of this could be there with the matrix.org protocol. The matrix protocol saves the comments and content in a directed graph, and that graph is copied to every instance, once one views it. It may not scale though. But it has benefits, such as encryption (making communities private or gated when under attack)
I’ve been out of this loop for decades, but can see a train wreck if this vulnerability isn’t addressed.
Matrix says, “The functionality that Matrix provides includes: Creation and management of fully distributed chat rooms with no single points of control or failure…”
I don’t know what ‘fully distributed’ means. But one potential way of securing everything might be through something like torrenting. Have all Instances on several servers, such that the loss of a single server or Instance couldn’t wipe out a community. If that happens more than a few times, I could see federating setback considerably.
That’s my two cents, and I’ll leave it to the smarter and more capable folks to resolve.
