When iterating over submissions for a profile, previously
it was possible to iterate past the end of a given profile's
submissions, and into the next profile's. This was fixed by
setting lower & upper bounds rather than leaving them
open-ended
Currently federation requests + accepts + rejects + undos all work
Federation blocking works also
Profiles can federate their text and images, provided federation was
enabled before profile creation. Looking into backfilling existing
profiles is TODO
