ou might have seen that we’ve been defederated from beehaw.org. I think there’s some necessary context to understand what this means to the users on this instance.
How federation works
The way federation works is that the community on beehaw.org is an organization of posts, and you’re subscribed to it despite your account being on lemmy.world. Now someone posts on that community (created on beehaw.org), on which server is that post hosted?
It’s hosted on both! It’s hosted on any instance that has a subscriber. It’s also hosted on lemmy.ml, lemmygrad.ml, etc. Every instance that has a subscriber is going to have a copy of this post. That’s why if you host your own instance, you’ll often get a ton of text data just in your own server.
And the copies all stay in sync with each other using ActivityPub. So you’re reading the post that’s host on lemmy.world, and someone with an account on beehaw.org is reading the same post on beehaw.org, and the posts are kept in sync via ActivityPub. Whenever someone posts to that community or comments on a post, that data is shared to all the versions across the fediverse, and these versions are kept in sync. So up until 5 hours ago, they were the same post!
“True”-ness
A key concept that will matter in the next section is the idea of a “true” version. Effectively, one version of these posts is the “true” version, that every other community reflects. The “true” version is the one hosted on the instance that hosts the community. So the “true” version of a beehaw.org community post is the one actually hosted on beehaw.org. We have a copy, but ours is only a copy. If you post to our copy, it updates the “true” version on beehaw.org, and then all the other instances look to the “true” version on beehaw to update themselves.
The same goes for communities hosted on lemmy.world or lemmy.ml. Defederation affects how information is shared between instances. If you keep track of where the “true” version is hosted, it becomes a lot easier to understand what is going on.
How defederation works
Now take that example post from earlier, the one on beehaw.org. The “true” version of the post is on beehaw.org but the post is still hosted on both instances (again, it has a copy hosted on all instances). Let’s say someone with an account on beehaw.org comments on that post. That comment is going to be sent to every version of that post via ActivityPub, as the “true” version has been updated. That is, every version EXCEPT lemmy.world and sh.itjust.works. So users on lemmy.world and sh.itjust.works won’t get that comment, because we’ve been defederated from beehaw.org. If we write a comment, it will only be visible from accounts on lemmy.world, because we posted to a copy, but our copy is now out of sync with the “true” version. So we can appear to interact with the post, but those interactions are ONLY visible by other lemmy.world accounts, since our comments aren’t send to other versions. As the “true” version is hosted on beehaw, and we no longer get beehaw updates due to defederation, we will not see comments from ANY other community on those posts (including from other defederated instances like sh.itjust.works).
The same goes for posting to beehaw communities. We can still do that. However, the “true” version of those communities are the ones on beehaw, so our posts will not be shared to other instances via ActivityPub. And all of this is true for Beehaw users with our communities. Beehaw users can continue to see and interact with Lemmy.world communities, but those interactions are only visible to other Beehaw users, since the “true” versions of the Lemmy.world communities (the ones sent to/synced with every other instance) is the Lemmy.world one.
Communities on other instances, for example lemmy.ml, are unaffected by this. Lemmy.world and beehaw.org users will still be able to interact with those communities, but posts/comments from lemmy.world users won’t be visible to beehaw.org users, as defederation prevents our posts/comments from being sent to the version of these posts hosted on beehaw.org. However, as the “true” version is the one on the third instance, we can still see everything from beehaw.org users. So we see a more filled in version than the beehaw users.
Why can I still see posts/comments from beehaw users?
Until they defederated us, posts/comments were being sent to lemmy.world, so we can see everything from before defederation. After defederation, we are no longer receiving or sending updates. So there are now multiple versions of those posts.
Why can I still interact with beehaw communities?
This won’t ever stop. You’ll notice that all posts after defederation are only from lemmy.world users. You won’t see posts/comments from ANY other instance (including instances that ) on beehaw.org communities.
Those communities will quickly suck for us, as we’re only talking to other lemmy.world users. Your posts/comments are not being sent to any other lemmy. I highly recommend just unsubscribing from those communities, since they’re pretty pointless for us to be in right now.
Why do I still see comments from beehaw users on lemmy.world communities?
Again, comments from before defederation were still sent to us. After defederation, it will no longer be possible for beehaw users to interact with the “true” version of lemmy.world communities. Their posts/comments are not being sent to any other lemmy. They also aren’t getting updates from any other lemmy, as the “true” version of those communities is on our instance.
Why do I see posts/comments from beehaw users on communities outside lemmy.world and beehaw.org?
That’s because the “true” version of those posts is outside beehaw. So we get updates from those posts. And lemmy.world didn’t defederate beehaw, so posts/comments from beehaw users can still come to versions hosted on lemmy.world.
The reverse is not true. Because beehaw defederate lemmy.world, any post/comment from a lemmy.world users will NOT be sent to the beehaw version of the post.
This seems like it’s worse for beehaw users than for us?
Yes. In my opinion, this is an extraordinarily dumb act by the beehaw instance owners. It’s worse for beehaw users than for us, and will likely result in many beehaw users leaving that instance. They said in their post that this is a nuke, but I don’t think they fully assessed the blast area. Based on their post, I don’t think they fully understand what defederation does.
A lot of people are missing the point of their defederation, which is a lack of proper moderation team and tools for the sudden scale they are exposed to as one of the most popular place of discussion with the rexxit with them harboring some of the most active communities around.
Their issue is mainly bad actors, trolls and harassers coming from those big instances and overwhelming them.
Defederation is the big-nuke symptom of a wider fediverse problem, a lack of moderation tools and readiness for scale, that I also saw happen a lot on Mastodon. I followed the infosec instance and they basically ended up having to defederate the biggest mastodon instances for a few days at a time when stuff like spam and cryptobro DMs ran rampant. I’ve received many of those so I can tell you that it’s pretty real.
Construing their decision as a desire to fracture the community is missing the actual reason they’ve tried to articulate. It’s a temporary stopgap for the 4 admins who just weren’t expecting the sort of volume and associated misbehaving problems they are suddenly getting.
Overall, Lemmy is getting through a pretty intense “shit just got real” moment. Please bear with it, people are working really hard at solving this from what I can see.
This is the first time I’ve heard someone call the exodus from reddit “rexxit.” I haven’t been on lemmy too much yet so maybe it’s a common term I I’ve just missed but I love it.
I’m by no means the one who coined it. I just read it someplace else, but I find it fitting too!
Thanks for this explanation, this makes a lot of sense and makes me less concerned about the whole thing.
Serious question though, if a server defederates, do the communities hosted on other servers just become completely un-moderated? This seems like a serious liability for the overall community.
I’m not the most savvy person there but it simply means to me that the defederated server cannot post or interact with the matching server. Moderation still works on both ends, enacted by their respective teams. This is akin to a server-wide “mute” button directed to content from another server.
There are plenty of instances that let you sign up instantly. To achieve that goal, they’d need de-federate with all such instances. Which they can, but I still think that’s a bad idea.
I believed their intentions were good at first, until I’ve read/seen how they treat users who dissent at all, and even chastise and accuse users who ask for clarification of rules as outing themselves as a bigot. That includes admin responses to users there genuinely asking about rules with terribly vague wording…
That place is on a fast tract to becoming a shit reddit says clone; not a clone of reddit in general…
I’ve seen SRS, neogaf and resetera follow that sort of route so I get where you’re coming from.
I’ve yet to interact a lot with beehaw so I reserve judgment on that front though. As you said, I think their defederation comes from a good place, having seen the same happen to a lot of mastodon instances.
I do know I certainly won’t be interested if beehaw turns into the same kind of abuse-ridden, toxic hellhole as the above, that’s for sure.
