I think that in order to avoid other instances having a meltdown, when a message is posted to a user inbox it should reuse a temp-id that that user actually followed at some point in the past. But you just have to keep an inventory of followed ids and grab the least recently used for the purpose of posting to a given instance.

The only invariant is that ID must be preserved inside of a thread.
