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.

My second day using Lemmy and infighting is already destroying it.

What was their reason for defederating? I tried to read their post and it didn’t make sense to me.

To be honest, as time went by and a few of my subreddits I frequented started to get brigaded by transphobes and fascist bawbags (Scotland and unitedkingdom subs are a great example of this) I stopped participating altogether in them.

I found the casualuk sub and that became pretty much the only place I’d comment/post. It felt like a much closer-knit community and I’d much rather have that than a massive community that may not feel as β€œhomely” if that makes sense.

EDIT - I replied to the wrong post, I've not had a coffee yet.

Seems like there should be a notice when a community is just a copy that isn't being updated anymore, to encourage people to abandon it and use one that is updated across instances. Or discourage them from subscribing to it.

Man this is starting to sound like reddit 2.0 where everything is walled off depending on what your subscribed to

[–] m3t00@lemmy.world 16 points 2 years ago

similar to truth.social is a never federated, modified mastodon instance. good luck

[–] abrr1sz@kbin.social 15 points 2 years ago (3 children)

Thank you, that is a great explanation.

I do get where Beehaw admins are coming from. They want their instance to be a tight-knit safespace, and it is pretty hard to accomplish when there are only several admins dealing with an insane wave of newcomers. Unless Lemmy moderation tools get better, that seems like an OK temporary solution. Though, it is still kinda unfortunate that federated services, while being a great idea overall, are so prone to balkanization (that is, essentially, the fragmentation of mastodon situation all over again) but it gives user choice.

In that case they shouldn't have been on the Fediverse to begin with.

[–] sangle_of_flame@lemmy.world 12 points 2 years ago (1 children)

why not? the thing about the Fediverse, once again, is that you get to choose who you want your instance to associate with

they temporarily don't want to associate with big instances with loose registration requirements, and it's because they're afraid that they wouldn't be able to handle any possible flows of bad actors from those instances with how small their team is and how barebones the Lemmy mod tools are currently

which sounds really reasonable to be quite honest

Why did they defederate us?

[–] Astrealix@lemmy.world 14 points 2 years ago (6 children)

They don't like how Lemmy.world and sh.it just.works have no barrier to setting up an account

[–] hskrnut@lemmy.world 19 points 2 years ago (6 children)

That's incredibly silly. Are they seriously not interested in gaining the huge influx of reddugees (still workshopping that one), this is the moment for Lemmy to gather a critical mass that has the possibility of attracting a large scale migration to the open distributed platform over the next couple years.

Amazing post with great info, thank you! There literally nothing in UI to let people know this is how it works tho and relies on words of mouth sharing. Communities essentially look exactly the same but like there's been no activity unless lemmy.world users post in it so you have to be able to guess posts are on a defederated instance or be hypervigilant in checking usernames if you haven't seen any posts about it, or are a new user in a week when this is t discussed as frequently. This is a huge oversight tbh and leaves me feeling a little uneasy. With more questions.

For example the LGBTQ community hosted on beehaw. Hypothetically say all of us genuine users who are aware of this unsubscribe because we find other communities that allow us to participate with a wider community. The shell community is still there, using beehaw branding, looks like a legit LGBTQ space but is now exclusively populated by trolls and unfortunate users who have missed announcements that this has happened. Nothing in the UI informs anyone posting or commenting there that it is not the true instance, and therefore no longer moderated by the owners.

Unaware user who already subscribed before the defederation posts a topic they want to discuss in a few weeks time, and suddenly they're flooded with highly upvoted troll responses That post ends up on the lemmy.world local/all page and is broadcast to other users who may not be aware, and a lot of new users who have no idea this ever happened. Now Beehaw is known as a hub for homophobic trolls that allows queer users to be trolled, and the trolls know they can get away with it in that community. Sure, eventually someone will come in to let that user know what's up and where to go, but by that time the damage is already done.

That also leads me to question how reporting works for this type of thing. If I report a user for breaking sub rules on the false version, who does that report go to? Is it a random lemmy.world mod/admin because we are both lemmy.world users in a community without beehaws mods or is it lost to the ether because there's no longer a connection to beehaw mods? If it goes to world mods, what if someone violates the subs rules that are still shown on the false instance, but not lemmy.world rules? My understanding was that moderation happened in communities by the host instance so does that mean these shell communities are completely unmoderated? That makes me feel very uncomfortable that these shell communities are even still available to world users, if it is the case, and should be cause for a mutual defederation until it's addressed but I'd like to have my reasoning corrected here if I'm off base. I'm still learning but this has me a little concerned so would appreciate being corrected if I'm wrong.

Its convenience. 99% don't care about anything apart from getting what they need. The blackout caused them inconvenience so its therefore annoying. Its the same attitude that can appear when workers take strike action.

[–] scorchingheat@lemmy.world 14 points 2 years ago (6 children)

Say I never read about these news: am I able to somehow see that a community belongs to a defederated instance, or do I have to guess based on the (lack of) new activity?

@AgentGoldfish

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.

Maybe I'm misunderstanding something, but how is it "worse for them"? Sure, if your goal is to create a big community, it's obviously bad, and perhaps it will lead to the death of that community. But their main goal isn't growth, it's having a "save space" and highly moderated community.

In your opinion, how should they have acted to achieve that goal when according to them, they are not able to moderate that much content at the moment in a way they want to? Lemmy.world allows any user to register without any vetting and is one of the biggest communities, does it not make sense to temporarily block content from here to decrease the amount of content to moderate?

I was just poking around a bit over at beehaw, earlier. and I got the STRONG impression that they really weren't in a position to deal with the sudden influx of users: not enough mod team, not enough money, not enough spare time in the day for the few people running it. I'm not holding that against them, that's to be expected in Fediverse spaces, which I gather intend to spread the load across thousands of instances, not just one.

Is this just them trying to get things under control, or was there some other problem?

[–] TheAmishMan@lemmy.world 13 points 2 years ago (1 children)

I think this is the best explanation of how federation works that I've seen so far. Really appreciate it. So would it benefit us to use an account for me different website to get the benefit of both communities? Is there a way to be essentially logged into two accounts at once so that you can see separate federated communities all at once?

If you look at the table on Awesome Lemmy Instances, Beehaw is far and away the most block-happy instance around, blocking over 70% of all instances in the Fediverse. They seem to see it as the defacto way to manage their instance.

Makes sense since, as other users have pointed out, the whole instance seems to be run by only a handful of the same Admins/Mods, so they are likely stretched very thin and are just taking the biggest swings they can to manage everything. They either need a major overhaul to their approach or that instance is going to fade into nothing.
