I might follow you randomly. I'm doing it to make my instance federate more, share the love.
it does make me a bit wary that eventually I too might feel like I picked the ‘wrong’ server if a defederation culture becomes common in the lemmyverse
Welcome to the fediverse; you either step in line with the “nice” instances or end up as one of the “usual suspects.” You can skirt the line between them for a little while as a super small or single user instance, but you’ll eventually join one side or be forced onto the other.
On editing posts, not sure if lemmy has an extension of AP but edits function by sending a delete and the revisions are just a new post altogether. Instances that reject deletes (they can be a performance hog) will see all your edits as different posts.
