So, to explain in more detail: I read about a new community on newcommunities and I decided to search for it so that it started federating with Kbin.
However, when I visit the community on lemmy.world, there are already 32 posts from before the community became visible on kbin, but I can only see the posts that were made after I “discovered” the community on Kbin.
Yes- if anyone interacts with those posts after the community has been federated then the entire post gets sent over. eg: someone “likes” a comment or posts a new comment.
I see. I assume you mean the interaction has to happen on the remote side then, since we can’t see the posts on Kbin?
Correct. If someone on that instance, or who is federated with the content on that instance, can do it. If you use a lemmy.world account and upvote all the posts they should federate to your instance.
I just tested it with my account on lemmy.world, and the posts do indeed show up on Kbin now.
That’s really good to know. Thank you so much for the explanation!
Interesting, it seems to work the same way between Lemmy instances. It would be nice if I could force a more thorough federation, but it’s good to see most content will eventually come through on its own time.
