In the graph above I’ve arranged the 28 Threadiverse instances with at least 200 monthly active users (MAU)—orange instances running Lemmy, green Piefed, and red Mbin—on the basis of which instances they defederate.

Each instance has its MAU count listed below it, sourced from the latest MAU figures at Fediverse Observer, with adjustments made to the totals for Piefed (due to undercounting by outdated instances, as noted here; I used @Vicinus@piefed.zip’s suggested estimate of 7,200 Piefed users) and Mbin (due to tardigram.com having a duplicate listing).

After adjustments, there are an estimated 43,287 monthly active Threadiverse users (35,184+7,200+903), of whom 87.84% are on the 28 largest instances. The percentages listed alongside the MAU figures correspond to each instance’s share of the total MAU count.

Defederation data was sourced from Federation Checker. The tool doesn’t support Mbin instances, so I left fedia.io in its own category. If any defederations are missing, feel free to let me know. Ideally such a chart should also include community blocks to better illustrate which instances block what, but that data doesn’t appear to be as easily searchable.

I also noticed cases of some instances being listed as being defederated by another instance, despite not appearing on the defederation list for that instance (i.e. reddthat.com and lemmygrad.ml are listed as being mutually blocked, despite neither having the other on their block lists). In testing that federation, I noticed that !wholesome@reddthat.com did not federate to Lemmygrad while !memes@reddthat.com did, so clarification on that matter would be helpful.

While I’ll update my generalized chart as needed to correct errors, perhaps at some point an automated federation mapping tool similar to the one feddit.de formerly hosted could be developed to more completely illustrate instance federation.

    Come to think of it:

    I still remember when Lemmy was fairly new. Before $20M for the client API killed off all third-party Reddit apps, enshittifying Reddit to such a point that people left for the Threadiverse in droves in protest (and looking for something that didn’t require either Reddit’s Web interface or the official Reddit app). When /kbin was still experimental (as opposed to dead), when Mbin and PieFed didn’t exist yet, but Lotide still did (although it was more or less a zombie).

    Back then, federation was optional on Lemmy. As in, Lemmy servers weren’t federated with anything by default. The admins had to manually add every single last Fediverse server, be it Lemmy, be it /kbin, be it something else, to an allowlist to allow it to federate with their server.

    Lemmy servers actually had public lists of servers they federated with (as opposed to lists of servers they had defederated, available on third-party websites).

    Not being federated with any given Lemmy server was the default back in the day. Most Fediverse servers were defederated from Lemmy servers because the admins of the Lemmy servers simply didn’t know that they existed. If you were lucky, then the admins occasionally checked their server logs, discovered Fediverse servers that they had never heard about, checked them and then added them to the list.

    It was only a while later that a new Lemmy version switched to federating by default, simply because the above was tedious and impractical.

      As others informed me, Hexbear still uses the allowlist system. While it seems like they’re pretty good about adding instances that don’t defederate them to their whitelist, six instances with over 50 MAU that don’t defederate them are effectively defederated from them due to not being on their whitelist.

    Very proud of lemmy.zip! Joined very early on cause the name sounded cool lol, and apparently a lot of others also did. If i remember right we had a vote on defederations and the only major one to happen(or maybe the only one, idk) was exploding heads which was a nazi instance with CSAM on it so that was obvious, even that was mainly cause of the CSAM. I really like the approach of users being able to block instances and communities rather than the instance deciding for me. I still have ml and hexbear blocked tho cause they banned me after i stood up for trans rights or something lol

        Oh i thought it was a perma ban. Also how can i check this? Cause i got banned after commenting about trans rights but i guess that wasnt why i got banned, tho the memes community ban might be that. 2 years is still insane tho. As for the other, yeah i was anti-ai in an ai community and not a vegan in a vegan community, but the way that is phrased is insane.

      I’m feeling the same way. I’ve bounced around a few places since joining. I started on midwest.social which was great for a while, but I think the instance grew more than the dev could keep up with. I started seeing connectivity issues and problems displaying content so I reluctantly migrated to .world to see what joining the largest instance would be like. The technical issues went away but I couldn’t figure out why I could no longer see /c/piracy until I realized that they’re a bunch of pushovers that defederated from dbzer0 based on some liability bogeyman. So I found myself on Lemmy.zip where I can police my own content and have no technical issues.

        i’ve been blocked for being pro trans in many communities.

        because I’m not pro-trans enough. so i must want to kill all trans people. or so their logic goes.

        it’s not really often a reflection of the instance or the community, so much as one really really angry user or a few, who have decided you’re the scum of the earth for voicing an opinion they don’t agree with 120%. you know, toxic nutbag users.

        extremists often thing anyone isn’t as extreme as them is committing a hate crime against them.

        anyway, i haven’t been banned anywhere since, since i blocked the instances from which those types of folks tend to come from. and they overwhelmingly come from a few instances, and making a post in their instances basically paints a target on your back and they stalk you across the fediverse because well, that’s the type of user they are. they could just… block you. but you know, that would be too simple, they need to feel like they have punished you for not agreeing with them.

    OK I think I get how to read this, once I understood the concept. Very nice work.

    Maybe it would be a little clearer if the lines where boxes overlap were just slightly offset – it would help see and distinguish them. For example if the blue box was moved down by just a little more than the width of the red lines, instead of being directly on top of them. If that makes sense.

      As many instances were already blocking the original lemmynsfw.com, I suspect most do it as a means of moderating the feeds of new users who might not want to see porn. An alternative to this (as mentioned by @Cricket@lemmy.zip) would be blocking access to its communities (versus the instance itself) by default, allowing users to see replies from fedinsfw.app users and unblock the communities should they wish to. In either case, I think user retention is better served by limiting access to such content to those who are specifically interested in it.

      For Multiverse and apparently Blahaj specifically, they defederate it over CP concerns due to it hosting a ‘Fautbait’ community.

        Hey thanks for tagging me, but let me clarify because that’s not exactly what I meant. Lemmy.zip doesn’t block any communities by default (as far as I can recall, at least). It blocks a couple of instances by default, and each user can remove those blocks if they wish. This is different from defederating from those instances because defederation cannot be controlled by users, only by admins, but it’s still an instance block, not community block.

          Thanks for the clarification 👍 Clarified with italics that what is being blocked is access to the communities, rather than a direct blocking of individual communities.

          The key distinction I wanted to highlight—aside from unblocking being an option—was that users from the blocked instance can still interact with communities on the blocking instance, compared to defederation.

        I always felt it was strange that it didn’t just happen at the client level. Should have had flags in the initial design and moderate to enforce. Just turn the default off on all clients people can turn it on if they want.

      As someone informed me, Hexbear is unique in that most of its “defederations” are just instances that aren’t on its approval list. Jlai.lu doesn’t defederate Hexbear itself, but isn’t on the approval list, so I guess that’s effectively a defederation; I’ll adjust the next version of the chart to account for that.

      The admins of feddit.org are afraid of german police coming for their servers and therefore ban content that is possibly illegal in germany quite liberally. Since german courts are sometimes weird this includes some Pro-Palestine content that could be interpreted as Anti-Israel (e.g. the chant “From the river to the sea…”). That topic in particular pissed of the dbzero community which then defereated feddit.org for being “Zionists”.

      The number is the number of instances within the box blocking the instance in question, whereas the percentage is the percentage of overall Threadiverse users that those instances represent. For instance, at least 64.01% of Threadiverse users (the actual figure is higher as the 12% of users on smaller instances are not accounted for) cannot access Hexbear communities or interact with Hexbear users.

          Ultimately most of the process involved adding additional columns to data extracted from Fediverse Observer, most importantly the block lists from Federation Checker.

          From there, the hardest part was figuring out how to lay things out in a way that enabled instances with similar block lists to be placed in adjacent groups in a way that’s understandable while leaving room for arrows.

          Have gotten helpful feedback so far, so hopefully the next version will be easier to understand.

          That’s not it either. The graph is only illustrating defederations (the arrows), not federations. In other words, the blue box and blue arrow mean that those instances in the box are defederating from the instance the arrow is pointing to.

      blahaj is in the black box (has defederated fedinsfw.app), in the blue box (has defederated Lemmygrad) and in the red box (has defederated Hexbear). No one on this graph has defederated pawb. The graph is a bit confusing on the first look.
