The biggest thing missing from Mastodon remains the ability to *actually* migrate an account between servers.

The follower-migrate feature is not enough. I need to be able to migrate an entire account, including posts. And I should be able to do it without the former server cooperating (because of course servers can go down). I should be able to get some sort of cryptographic cert I can send to a new server with my posts and they'll be like "oh yeah, this is real, migrating u now".

@mcc I understand why you want this. And at the same time, instances have policies that differ wildly.

Such a migration would be kind of a "retrofit posting" of content in bulk. How would you prevent me from first posting tons of hateful shit on a right-wing cesspit instance, followed by migration with a mass-import of that shit on an instance that has been well-moderated and ok, content-wise, so far?

@katzenberger Well, if you want a serious answer, the proposal for doing this I've already published involves sites running a distributed ledger of changes to user keys. In my original plan this was for key rotation and a kind of "forgot my password" feature, but it could also be used to track continuity of a single account across multiple servers.
