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 [email protected] 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 [email protected], 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
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.
I've noticed that viewing the same community through different instances even when not logged in can show different posts, comments, and votes. I'm not sure why either.
Someone correct me if I'm wrong, but once an instance has been defederated with another, you will not be able to see posts from users associated with that instance, even if they post into a community that you are federated with.
Why can't you maintain two accounts exactly? Also, lemmynsfw was having issues early on in their AI porn community where some very questionable stuff was being posted, requiring an explicit age rule to be implementing.
When you sub to a remote community that content is synced to your home instance. I wouldn't touch NSFW content being federated to an instance I own either. Way to much of a liability. Especially since I would be at the mercy of the random users Im hosting.
lemmy.ml is defederated from lemmynsfw.com, so they cannot exchange any posts anymore. You can see the federated/defederated list at the "instances" link at the bottom of the page. This is the flip side of fediverse: the power to moderate their communities and to chose whom to associate with is given back to the users, but it has the potential to create a "swiss cheeze" social network. To create a user, look for servers that have "free speech" as one of their community values, which would not defederate for ideological/nsfw reasons, and hope no one would defederate from them for being too "free".
2 days ago when I posted this, lemmy.ml and lemmynsfw.com still listed each other as linked on their instances pages. Then 1 day ago, lemmy.ml listed lemmynsfw as defederated.
But my complaint, that the posts and communities from other instances is "swiss cheesed" as someone else put it, still stands.
Yeah, I'm noticing a lot of missing posts/comments/votes too now. It's as if the federation protocol is taking a long time to catch up, even if nothing is otherwise blocked. For now I have to browse the communities I like on their host servers through https://lemmyverse.net/, then copy the fediverse URL of the comment I want to reply to, and paste it into my instance's search box. That usually syncs it up and I can reply then.
