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the latest MAU figures at Fediverse Observer, with adjustments made to the totals for Piefed (due to undercounting by outdated instances, as noted here; I used @Vicinus@piefed.zip's suggested estimate of 7,200 Piefed users) and Mbin (due to tardigram.com having a duplicate listing).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.
Hexbear blocked you for being pro trans? I find that hard to believe.
I disagree with them on a lot but they are a very pro trans group of people
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.
