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.
What they want is moderation. Unlike microblogging where you post to your followers, I think that running a public debate platform like Lemmy without controlling who enters is a horrible idea. That's why they posted a statement with the clarification that this defederation need not be permanent.
Reddit is a public debate platform (even before Lemmy) and they don't control who enters in any way, is that really a horrible idea as you say?
I mean, Reddit very much controls who enters. Not so explicitly as to have a survey or something, but they very much have mechanisms against bots and people who try to circumvent bans for example.
Yes but that's not the same as controlling who enters, not in this context.
Beehaw has a very strict application form, you have to write a lot on it and they decide if accepting you or not based on what you write, that's controlling who enters. Reddit doesn't do that.
Lemmy.world has nothing like that either, it does have a captcha in which you write, but only as bot control as I understand it, it's not that they refuse you only because they don't like what you wrote. I guess sh.itjust.works is similar.
Beehaw feels like it wants to be the Lemmy version of Tildes. And just like Tildes, its desire to choke its own growth rather than risk having to actively moderate is antithetical to the idea of a social media platform.
If what they want is a club, well, they'll get a club. But they won't get an active platform.
What they don't seem to understand is that those undesirable people weren't typically undesirable in every single thing they said or did on Reddit. The ugly truth of that platform is you probably got lots of upvotes and replied to people you had no idea were alt right trolls or whatever. They likely upvotes many things posted by "shitty" people without knowing it.
The difference is reddit isn't curating based on beliefs and character. That's what Beehaw does. It is trying to screen the social aspect of social media rather than actively moderate it.
They want a club, not a social media site.
This is not a question of fact, but of opinion. And yes: I've never been significantly active on Reddit, all the notifications I get there are spam porn accounts that follow me in.
To me, open signups seem wrong for a volunteer moderated service.
You have a right to your own opinions of course but "a volunteer moderated service" is exactly what reddit is, unlike facebook or other similar platforms, reddit mods are not employees, they're users like everyone else, volunteering to do the mod job, for free.
That's fine, I disagree but you can join beehaw if that's what's best for you. I just feel this creates unnecessary tribalism.
I'm not on beehaw, I've never been - and I'm almost fine, where I am π π
But Reddit has open registration.
We don't need no "moderation", we don't need no thought control.
If you don't want it, that's absolutely fine - you just have to respect that others don't share that opinion and cut the line since it's hard to find a shared Fediverse of opposite ideas. Unmoderated instances have always been seperated in Fediverse-microblogging and I really don't see why history shouldn't repeat in this case.
Who is talking about Reddit?
Are you aware this is a different place?
