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.
The idea is that every instance is basically responsible for their own users. And beehaw didn’t have confidence in the moderation of shit just works and lemmy.world and couldn’t keep up with banning them on their side. Thats why they defederated.
It’s correct what you say, but the idea bugs me the more I understand it.
It feels like guilt by association. The actual cause is the behaviour of specific, individual users but the repercussions are equally felt by other users from the same instance. These other users can have nothing in common with the causing users, or might have even opposed them in their wrongdoings.
There is also a level between users and instances; communities. Maybe the problem was with one specific community, yet all other communities who happen to live on the same instance feel the same consequences.
Defederating individual communities would feel better for me, but ultimately I think a problem caused by individuals should be solved with these individuals, not with groups which are more or less meaningfully associated with those individuals.
The problem is that we don’t just have individuals but anonymous individuals. Even if you block, ban and defederate users if they can just turn around and put a +1 on the end of their Gmail account and go on spamming, and posting unwanted content. You have to act against the people enabling this.
There is a reason why some moderation tools aren’t available yet but a application system is. The fediverse is not supposed to be a group of unaccountable anonymous individuals. It’s supposed supposed to be an actual market place of ideas with bars where if your customers shit on the tables all the time the local health department will shut you down.
Unfortunately Lemmy doesn’t have that kind of fine tuned control yet
As I understand the problem from their side is that to get an account on Beehaw, you have to go through an approval process. If a user there starts violating their policies, they can be banned and it’s harder and slower to make a new account to get around the van because of the approval process. But getting an account on the other two instances is automatic and instantaneous. If a person from this instance starts violating Beehaw policies in a post there, and Beehaw mods ban them, they can make a new account here and be back there causing trouble in seconds, which is apparently what some people did.
The moderation tools are apparently pretty coarse right now, so they could essentially ignore it or defederate from us, and they chose the latter.
People out to specifically troll beehaw will just keep going to other instances until beehaw completely blocks itself off from the entire fediverse.
I don’t think the solution here is to defederate, but just to get more moderators (and better mod tools).
undefined> It feels like guilt by association. The actual cause is the behaviour of specific, individual users but the repercussions are equally felt by other users from the same instance.
That’s why I always thought that the ideal scenario for federated web is to have instances that are either single-user or are down to friends-of-friends level of members (say, under 100 users per instance), so that there can be social accountability and if you have a bad actor on your instance, then it’s easy to kick them out and preserve your reputation. Bad actors will concentrate on their own instances and they can be defederated without collateral damage.
So, if Beehaw’s registration model is invite-only (that’s what I gather from this thread), then I think they probably have the right approach to federation; they are vouching for their users and they are responsible for making sure that they won’t be damaging communities across the federation.
Sure, there’s no issue with that. I think most people agree that Beehaw can run their instance as they see fit and even understand their intention of trying to keep out trolls. We’re just also saying that it’s not the most efficient way to deal with the problem, and mainly it punishes Beehaw users as far as I can see.
Beehaw has the largest communities by an order of magnitude and without a coordinated effort that is probably not going to change. The losers here are absolutely lemmy.world and sh.it
This makes perfect sense.
