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.

      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.

        Yep. It’s just stupidity especially now. I don’t understand why someone would stay there and not go back to reddit for a walled garden experience?

        Their announcement is decent, and explains their reasoning.

        They care about the general environment. The influx of users including some bad actors means they can’t effectively moderate and block them. They value a controlled safe space over influx of random users [with some bad actors].

        There’s a lot of soft moderating that happens, where people step in to diffuse tense situations. But it’s not just that, there’s a vibe that comes along with it. Most people need a lot of trust and support to open up, and it’s really hard to trust and support who’s around you when there are bad actors. People shut themselves off in various ways when there’s more hostility around them. They’ll even shut themselves off when there’s fake nice behavior around. There’s a lot of nuance in modding a community like this and it’s not just where we take moderator actions- sometimes people need to step in to diffuse, to negotiate, to help people grow. This only works when everyone is on the same page about our ethos and right now we can’t even assess that for people who aren’t from our instance, so we’re walking a tightrope by trying to give everyone the benefit of the doubt. That isn’t sustainable forever and especially not in the face of massive growth on such a short timeframe.

        Explicitly safe spaces in real life typically aren’t open to having strangers walk in off the street, even if they have a bouncer to throw problematic people out. A single negative interaction might require a lot of energy to undo.

            On Mastodon there was this whole thing about users calling themselves Twitter refugees, and people expressing their displeasure with the term. It does feel a bit inappropriate to equite youself with actual refugees. We’re just moving from website to another.

              It’s language. In language, context is important. We don’t have infinite words, so I don’t agree with the idea of one singular context claiming sole ownership over any given word. There’s reasonable respectfulness towards people going through hardships, but there is no point in allowing any particular context to “own” a word that serves a whole lot of purposes.

      The barrier being what you’re supposed to write when you sign up to convince them to bring you aboard? That anyone can make up? yeesh
