Why do some posts and communities not show up on all instances?

Reddit refugee and Noob to lemmy/fediverse here.

For example, I'm currently logged into my lemmy.ml account, and subscribed to !anime@lemmy.ml and I can see a lot of posts there. I can also see that it has over 3K users.

If I log into lemmynsfw.com, and look at my subscription to !anime@lemmy.ml, I only see a few posts, and I know there are several that are missing. Also, it tells me that the community only has 8 users.

Is this synching problem common in lemmy, and/or the fediverse in general?

Do I have to create a new account on each server hosting communities that I want to keep up to date on?

I’m not sure but it might be that they defederated? A fair number of instances don’t federate with nsfw ones. Here’s an explanation of defederation: https://lemmy.world/post/149743

Both instances list each other under Linked Instances, on their respective instances pages, fwiw.

As far as I can tell, this is a defect in the design of Lemmy. When you go to lemmy.example.com/c/cats

Apparently the server only shows you /c/cats posts made in that server. This annuls the social part of this social media network.

lemmy.example.com/c/cats must show all /c/cats post of the entire fediverse.

Nobody cares about only /c/cats on some random instance like lemmy.example.com.

If this is not fixed soon, the Reddit user base will realize Lemmy is broken and go back to Reddit, just like twitter users did with mastodon when they realized it's unusable.
