"Defederated" is not something that happens to an instance, it's a choice that other instances make. There's no "globally defederated" state. If your server (Server A) is blocked by Server B, then no, you can't move to Server B. But you can still move to Server C that doesn't block you.

Well so this is kind of what I was getting at. It feels similar to an email service being blocklisted, only in this case, you really _can’t_ move your content because at the end of the day, a group of federated instances will also be wary of instances without reputation, as much as those of ill repute. So no, in reality, you can’t move your content, or if you can right now it’s a foible of the system as it is today and will not continue as such.
