For example I would selfhost Mastodon with me@fedi.com but then decide to change the server software to GoToSocial but keep the same me@fedi.com. Would everyone who was following me@fedi.com keep me in their follower list or would whole fediverse crash?
I changed kbin.earth from kbin to Mbin, and it’s been working great. It definitely helps that Mbin is a fork of kbin.
