BLOCKchain blocklist advisory
DzukLast updated 12th July 2018

This List is changing
This list is slowly transitioning to a better and easier to read version on GitHub here.
At the same time, this list is also getting too long for Telegram. So slowly content will be transitioned over to the new list. The GitHub has more links, but also doesn't have some of the evidence that's been posted here yet.
Hey, this is a list of instances which you might want to block to protect your instance from shitty and threatening behaviour and illegal content.
Each instance is loosely grouped by the reason you might want to block them for, with some accompanying text explaining why it's a problem if you're unsure about what I mean.
Unless the reasons to block are self-evident from looking at the instance, I try to give links and/or screencaps of evidence (apart from when it's something like Lolicon, for obvious reasons).
If you want to look at some awesome instances instead while learning about how instances work, check out my guide on that!
(Btw, I am a moderator of a.weirder.earth and this list mostly reflects our instance blocks, but there are a few differences for certain reasons.)
Content Warning
This post will reference some unpleasant stuff on all kinds of things ranging from hate speech to child porn. There are also some screenshots of fascist, violent or ignorant ideology or opinion, (but not porn or illegal content). If you're not feeling good to read or see that kind of stuff, then I recommend you stop reading.
Links that contain or may contain distressing imagery (gore, violence, etc.), NSFW or lolicon/CP are un-hyperlinked for your convenience, but unpleasant discourses, ignorant, violent or fascist opinions, etc. are not.
FAQ
Check out my Instance Blocking FAQ if you have objections to this practice or are unsure about the nature of it. It doesn't cover everything, but it might help.
This list mostly covers English-speaking instances.
I'm trying to kick my monolingual disease but until then, the instances on this list will be generally English-speaking instances. If you make a list for other languages let me know so I can link to yours from this page.
This list updates!
You can follow @blockchain@monsterpit.net for updates.
If you know of an instance similar to these that you want to add and want to forward the evidence to me, I'll be happy to take it at @blockchain@monsterpit.net. This list will update as I find more.
Here is the list!

Harassment and/or directly shitty behaviour towards other instances
There seem to have been other instances on this list that also have engaged in harassment with other instances, but these are the only ones I could find the evidence for.
(Formerly used the domain noagenda.social. You might want to add this to your domain blocks too just to be sure.)

Spam
This is an instance where no valid email address is required to make an account because there is no email verification process. It is home to spam accounts like https://2.distsn.org/@mastodon_user_matching.
Fascist, violent speech and zero-moderation spaces
These are safe spaces for violent and/or shitty ideologies and speech - including fascist (such as Alt-Right, Identitarian [another link]), Neo-reactionary, GamerGate, and so on. They also tend to contain illustrated sexualised depictions of minors, untagged NSFW and more.
It's generally self-evident from looking at the homepages or descriptions so I didn't give specific evidence links, but if you want to check for yourself you will need to be careful as illustrated sexualised depictions of minors do exist on many of these. According to other sources, many of these places have also harassed people in other instances.
These are the kinds of instances where suspending would be pretty appropriate.

Less violent speech spaces
They aren't as extreme or as obvious as the previous list, but they still totally have these elements, so I'm going to give evidence links to make it clear. I don't know if these instances contain lolicon other than the ones I specifically mention (community.highlandarrow.com probably doesn't), so you might want to be on the safe side with the media blocks.

Most of this is fine but there are the occasional crappy discourses, shown in the links below. Apparently this instance's software apparently does not have moderation tools either so they are literally incapable of moderating themselves to an extent.

The two main users of this instance has some really fucked up and fascist-leaning opinions and posts.

Dangerous Conspiracy Theories
Conspiracy theories can be a complicated subject, and I don't mind some degree of speculative stuff, but generally what crosses the line for me generally comes under one (or multiple) of these:
- It promotes psuedoscience
- Is a hate group conspiracy theory (ie. 'International Jewry', 'Cultural Marxism', Holocaust Denial)
- Is one that necessitates or involves hatred (ie. racism, bigotry, etc...)
- It generally gets people hurt or fuels violence

Unwilling to moderate hate speech and shitty content
Instances that aren't overtly fascist spaces or fascist safe spaces, but they do say that they want to moderate as little as possible, with the only thing they're really willing to moderate is what's illegal for them. That also usually includes harassment.
The problem with that is that leaves out fascism, sexism, racism, homophobia, and other forms of bigotry. So while they aren't necessarily doing the bullshit routine themselves, they are basically as fine with it as the rest of them.
This isn't the same as just not having a CoC or not having a detailed CoC.
Instances that simply have no CoC or no detailed CoC against violent speech aren't automatically on this list because an instance can still act against violent speach without one. This list is only for instances whose administrators have systematically ignored or accepted instances of violent speech, or have made it clear that they would act in this way if that were to happen.
Instances that have made it clear that they won't remove violent individuals, but at least will silence them from their end (so they don't bother other instances) are also not on this list.

Enabled shitty behaviour, weak harassment policy.
Someone on this instance was found posting hate speech, multiple people (including admins/moderators in mastodon.social and anticapitalist.party) saw it and talked to the admin of this instance (@wonderfall), who defended the person posting them. The offending user has since been deleted (don't know why), but @wonderfall has defended their original stance. I don't know if they have continued to this day.
The about page more recently has added some kind of policy for moderating hate speech and harassment, but the admins are still have a very hands-off policy and one I personally don't think is acceptable. You'll have to decide how that is for your own instance.

This is an unusual one. Normally the instances I block are outright hostile or are very forward with their hostile opinions, but my interactions with this instance's admin have been very fine and pleasant. Many instances like the ones I've moderated have often federated with this instance for a while (or still do), and while it does claim to moderate on the front page, it's not moderated sufficiently to deal with shitty users and posts.
This does have a few fine users, but it is also home to a lot of the stuff you've seen in the instances before this one on the list.

Other Hostile Admin Conduct
This is a miscellaneous group, and each instance is here for their own very specific reasons. I recommend you check out each instance's file.

Unresponsive to moderation messages
Instances that haven't responded to moderation messages in my personal experience. (Take this with a pinch of salt.)


I sent a message to the instance's admin about the user pictured above. They did not respond for a week while being active at the time. Trying again also yielded no response. While this user appears to be deleted, another from the same person has arisen in it's place and I still didn't get any response from the admin about any of this.
Complacency with harassing users
Admin would not act based on a legitimate moderation request involving a user jumping in on a harassing post thread. I tried to explain to them why it was a shitty thing to do, but they were insistent on not doing anything.
Unflagged / Potentially Unflagged NSFW
- porntoot.com (https://github.com/tootcafe/blocked-instances) (no longer seems to be a Mastodon instance)
Illustrated sexualised depictions of people who appear to be minors
This isn't necessarily a moral judgement, but it is illegal in most western countries. (Notably while AFAIK this is not legal in Japan, a law was only introduced recently and it's not particularly enforced, which is where this often comes from).
This includes but is not limited to lolicon and shotacon.
This judgement has to be done by eye, not by whatever an accompanying text says. So if some context says the person is over 18, but they definitely look under 18, that is still going to be considered under this category.
With this list I am generally going by the word of mods and admins I trust unless I accidentally stumble upon it myself or it's self-evident from the instance description. I generally won't be linking to the material because it would probably be legally fraught for everyone to do so.
- baraag.net (https://elekk.xyz/@noelle/18828)
- social.allthefallen.ninja (lolicon and shotacon-oriented space; self-evident from instance description)
- Pawoo (pawoo.net) (Japanese law on this differs to western countries so it's legally fine for Pawoo to host shota/loli) (https://github.com/tootcafe/blocked-instances)
- social.homunyan.com (https://social.homunyan.com/users/ZettaiRyouiki/updates/4632, also that entire user. The admin has boosted an update from that user and the instance is very small so they seem fine with it.)
- preteengirls.biz (kinda obvious from the name... [1])
- mastodon.loliandstuff.moe (self-evident)
- wxw.moe (It has a loli-posting bot called AnimeGirlsBot. The instance is Chinese so I can't talk to the moderator about it but judging from their profile they are totally fine with it.)

Corporate-owned or corporate-sponsored social instances
This may not become a serious issue, but I think it could be a really important thing to keep an eye on for the future. I think that corporate ownership generally conflicts with the idea of social spaces as an emotionally supportive environment (how many of us left Twitter because it tolerates Nazis and doesn't have any real ethical or moral positions?).
They also conflict with the idea of intermingling, spaces with a cooperative relationship to each other (ie. our instances) - corporations expect to dominate 'markets', we provide services based on what we can afford to those who want and need them. I would say that our kind of social networking is potentially an existential threat to corporate social networking, and we shouldn't let them have an inch because they will take a mile. If they ever take an interest in decentralised social networking, they will only care about us insofar that we're good PR for them.
I'm not necessarily saying block these right now (I'm not apart from Pawoo, for other reasons), but I think keeping watch would be a good idea, especially if they become a thing in the West. They currently only seem to be a thing in Japan right now.

- Pawoo Music (made and run by Pixiv Inc. [JP])
- friends.nico (run by NicoNico [JP])
Advertising
Instances owned or used by corporations to advertise and post product updates. I wouldn't say block them, I just think they're better silenced so only people who want to see them will see them in the Federated Timeline.
