Why can I still see beehaw posts on my feed?
I'm with lemmy.world and I can still see beehaw recent posts and I can interact with them despite us being mutually defederated. How does this actually work?

That explains it thanks. I thought we were mutually defederated (that's what I heard anyway). So essentially, if I were to comment under one of their posts, their users won't see my comment?
From my understanding, in a federated scenario,
your home instance is making a copy of the remote instance.
Comments you make are on the local copy your home instance made.
Your instance tells the remote instance the comments made in your home copy.
Comments in your home copy are written to the remote instance.
Instances now have your comment when they copy the remote instance
Defederation breaks the process at step 3.
So your instance is still copying their remote content, and you can still see and comment on it, but those comments are only in your home instance. They can only be seen from people within your home instance looking at the same copy.
Thats how I understand it works, yeah. Beehaw wont pull your comment’s through
But would other instances (including lemmy.world) still see that comment?
I think lemmy.world users can see it, but nobody else can.
I’m pretty sure other lemmy.world users would see each others interactions, not sure how other instances would see it. I would assume others would, if they’re federated with world
I think not, even if other servers are federated with World, they are pulling the comments from Beehaw, so they wouldn’t see the comment. Your instance doesn’t check every other instance for the comments on a thread, just the instance that owns the community.
This is correct.
Comments made locally on an instance that has been defederated from the owning remote instance only exist on that local instance.
I’m not clear on what happens when refederation occurs…
I think that posts made when the instance was defederated will not be there, but posts made after will be. Correct me if I'm wrong.
I think that is true just like the question of whether posts made, federated, then deleted would remain outside the instance. I can imagine the server drain if it had to recursively search through all history everywhere that's connected to do such things. A refederated server, or even a newly online server simply shouldn't spike the network with pulls from weeks, months, years back.
This is why Kbin has the boost button in addition to an upvote. That's being debated on if it's the best way to do it, or if there's a need for a more integrated way to do the same thing. It basically pushes old content back on the federated "stack" to refresh new views. Perhaps Kbin and Lemmy upvotes should do the same?
