More info about this here: https://fedi.tips/why-does-someones-account-page-look-completely-blank-is-it-really-blankIf you follow a profile, your server will start noticing its posts made after that moment and will (eventually) start updating its follower numbers too.Defederating means when a server totally cuts off connections to another server. It can only be done by server admins.
