small44Many mastodon instances shut down. There’s always a risk that at some point the donations are not enough to sustain an instance. It could be very problematic if mods lose their communities when an instance shutdown.
Perhaps what we need is a backup code or some kind of exportable file with all our data (subbed communities, interactions, yadda yadda) which we can port over to a new instance if necessary.
MattMastodon does this (you can download a full backup of your entire account - although not sure about media) every 7 days, which can be imported into various other Fediverse platform accounts, depending on what they allow.
I suspect that all Fediverse platforms worth their salt will make this a core feature.
