My Fediverse blocklists	Documentation on which Fediverse blocklists I offer, how they are made, their differences, their caveats, and their intended use.	2023-05-02T00:00:54-07:00	html gemtext	title url The Fediverse https://pleroma.envs.net/notice/AVEkLIaUf7JXnJkz2m	true	ChangeFreq Priority daily 0.7

I moderate the "pleroma.envs.net" Akkoma instance on the Fediverse, as @Seirdy@pleroma.envs.net.

I maintain three main blocklists for the Fediverse:

The pleroma.envs.net blocklist

A large list of instances that I find worth suspending. After the first couple hundred entries (imported and then reviewed), I started collecting receipts. Since early 2023, every entry has documented reasons and receipts. I share these with multiple people in a collaborative document, but I don't share it publicly due to risk of harassment. Unlike the other two lists on this page, it wasn't made for general use (though you're welcome to use it as reference).

tier0.csv

A much smaller semi-curated subset of pleroma.envs.net suitable for the majority of instances wishing to uphold the Mastodon Covenant's moderation standards. I hope to make it a good starting point for your instance's blocklist, with wiggle room for your own adjustments. I encourage you to add and remove entries as you see fit. Regularly importing tier0.csv won't account for retractions; a sibling blocklist for tier-0 retractions exists for FediBlockHole users.

Note that this list is larger than the bare-minimum I recommend; that'd be FediNuke. If you're skeptical of imported blocklists, you should start there.

FediNuke.txt

A curated subset of tier0.csv, containing what I deem the "worse half" of it. This contains instances I really do recommend most people block, or at least avoid. I try to make it a suitable candidate for a "default blocklist", and use it as reference when I evaluate the quality of other blocklists.

This list is not comprehensive; to keep this list small, I excluded many really bad instances. I take into account not just severity, but also notoriety and likelihood of reaching/harming people on other instances (e.g. spewing toxicity in others' mentions, running blockbots, etc). Bad instances that mostly keep to themselves are less likely to cause problems for a new admin, and therefore less likely to get included in this minimal list.

Criteria are not set in stone. Instances well-known for causing significant problems for many other instances, particularly for instances run by and for marginalized groups, may be added.

Some of these lists are also sources for the Oliphant blocklists. {{}}{{}} describes them in his article {{}}.{{}}

This post is an attempt to document how they are made, their differences, their intended use, and especially their caveats.

{{}}

How Tier-0 and FediNuke work

My tier-0 list (mirrored to tier0.csv in the Oliphant repository) is a subset of the pleroma.envs.net blocklist. It contains entries that appeared on at least 11 out of 20 other hand-picked instance blocklists ("bias sources"), with exceptions detailed below. Not all Tier-0 entries have the same level of severity; a smaller list containing what I personally deem the "worse half" of Tier 0 is FediNuke.txt. Consensus builds Tier-0; severity builds FediNuke.

When I add a bias source, I may also increase the minimum number of votes required if I find that its blocklist is too close to (or mainly just imports all of) tier-0 or the blocklist of a bias source's blocklist. That's the reason why the threshold is 11 instead of 10.

Overrides

There were some block-overrides for instances with fewer than 11 votes. Here's how I went about overriding:

• If an instance has 10 votes, I may elect to add it after additional review instead of waiting for it to hit 11 votes. It still has 50% consensus at that point.
• If an instance is run by the same staff as another Tier-0 instance and has at least 5 votes, I may add it after asking other admins about it and getting multiple thumbs-up from admins who import tier-0.
• If an instance contains blatant/unapologetic bigotry (something really undeniable, like Nazi imagery or excessive use of slurs in violent/hateful/definitely-not-reclaimed contexts) with staff approval or involvement, I may add it to both tier-0 and FediNuke.txt after I get multiple thumbs-up.
• If an instance becomes risky even to many tier-0 instances (untagged gore, dox attempts, significant cybersecurity risk, CSEM, etc. with staff approval or involvement): I may add it to both right away, skipping any process.

Under ten controversial entries were excluded despite having more than enough votes, after consulting with other admins. Typically, these were instances that didn't pose a major safety risk, but did fail many admins' "vibe check" or exhibit major governance issues.

I also excluded Twitter mirrors such as BirdSiteLive and bird.makeup; I maintain a supplementary list for those.

Bias sources

Criteria for a bias source:

1. Has a public blocklist I can easily download.
2. Practices timely and proactive moderation: doesn't just wait for another instance start interacting and cause trouble, and updates more often than once a month. Evaluating this takes time.
3. Blocks at least half of FediNuke.txt.

The final tier0.csv isn't a pure representation of agreement between instances; it contains overrides and is merely a subset of the pleroma.envs.net blocklist. Other lists only serve to determine the bias used for filtering the pleroma.envs.net blocklist. The pleroma.envs.net blocklist is technically the only "real source". Other bias sources shouldn't be held responsible for the final tier0.csv contents. I'll explain my motivation for doing this in the next section.

Since accountability for tier0.csv rests on me rather than on other instances, I don't publish the current bias sources. Blame for any problems in tier0.csv should rest with me, not them.

Motivation for including personal bias

If tier0.csv were merely an unbiased list of the most widely blocked instances, then being on the list would become a self-fulfilling point of no return. If an instance gets blocked by enough other instances, then it shows up on my lists. If an instance shows up on my lists, it will get blocked by other instances which import my lists. If more instances block it...you get the picture. This leaves little room for retractions and mistakes. By making all my blocklists a subset of the pleroma.envs.net blocklist, I ensure only one party needs to be convinced to remove an entry.

Some instances migrate their domains. If the old instance was already deemed worthy of a suspension and the new instance maintains the same staff with no visible attempt to change its reputation, then I deem the new location to be as block-worthy as the old location and make an override. It's the same bad actors under a different banner.

Retractions

A separate list exists for retractions from my tier0.csv list. I don't add entries to my retractions list when I remove dead instances, or when an admin on a removed instance prefers not to be included in it (some wish to remain less prominent).

Intended use

The original goal was to make a blocklist appealing to instances with a more laid-back moderation approach, so that they would actually implement a decent blocklist and limit the reach of the worst actors. Unfortunately, the final tier0.csv blocklist is 350+ entries; this is still a bit much for the moderate instances.

I pared that down to FediNuke.txt, which contains instances that were both really bad and well-known. It's kind of hard to overlook how shitty each instance on the FediNuke.txt subset is. Common themes tend to be repeated unwelcome sui-bait from instance staff against individuals, creating or spreading dox materials against other users,¹ unapologetic bigotry, uncensored shock content, and a complete lack of moderation.

I think if you're starting a well-moderated instance, Tier 0 is a decent place to start (that's why it's in the standard CSV format). You should add and remove entries as you see fit. If you're making a client and want to give it a built-in blocklist, or are looking for a good "default" blocklist: FediNuke is a good option.

However: if your instance grows larger (or if you intend to grow): you should be intentional about your moderation decisions, present and past. Your members ostensibly trust you, but not me. See the "trust but verify" section for for more information.

Rationale for creating two subsets

I used to just make a Tier-0 list. Later, I added the FediNuke list. Some people have asked why I don't just use one or the other; if Tier-0 was big enough to warrant FediNuke, why publish Tier-0 at all?

I have two reasons for maintaining two blocklists:

1. I didn't feel comfortable placing some Tier-0 instances right next to, e.g., openly Nazi instances when they weren't at the same level of severity. FediNuke's existence establishes that some instances on the list are much worse than others. Maintaining multiple blocklists makes their subjectivity more obvious.

2. The lists can work together. As I previously mentioned, the division makes it easier for people to feel comfortable importing blocks. Some admins have found that importing FediNuke and gradually combing through the rest of Tier-0 is more approachable than an "all or nothing" approach.

Use FediBlockHole

The CSV format I use is the format used by FediBlockHole. I do this for two reasons:

1. FediBlockHole supports retractions: admins can configure a merge strategy to support downgrading an entry's severity, with the lowest severity (noop) being equivalent to a removal with an optional reason.

2. Oliphant's blocklists use my blocklists as sources, and are powered by FediBlockHole.

If FediBlockHole supports your Fediverse server (it currently only supports the Mastodon admin APIs), I recommend using that if you want retractions to work.

Trust, but verify

I totally get resistance to blindly importing blocklists; I don't actually feel comfortable going the "import and forget" route myself! The first couple hundred entries of the pleroma.envs.net blocklist started with a few imports, but all domains have since been manually reviewed. For admins who don't feel comfortable "outsourcing" their moderation to blocklist authors: I generally see pre-made blocklists as a starting point.

Importing FediNuke.txt and then individually importing tier0.csv entries after manual review is a decent way to balance two conflicting needs:

1. The need to verify suspensions.
2. Not having the time/spoons to verify all the entries.

Another option is to use some text-processing tools to find entries that are common between Tier-0 and another trusted instance's blocklist. You can import the overlap.

Finally, you could just do something else entirely. I never use "your blocklist is different from mine" as a block-reason; even "totally open federation" is never the sole reason for pleroma.envs.net suspending an instance. Suspending instances for not using my own blocklist feels wrong.

Before you decide to trust one of my lists, please read the "Mistakes made" section.

Mistakes made

Here, I publicly document all significant mistakes I've made in the process. I sort entries in descending order by date addressed.

One mistake hasn't yet been listed; I'll wait for approval from one of the people impacted.

Early April 2023: Oliphant's max list containing bad entries

I made a mistake that didn't have a negative impact on my lists, but did impact someone else's. Even if my own lists came out okay, the fact that I allowed this to happen should be enough reason for you to seriously question my judgement.

I work with {{}} when generating lists; we share ideas regularly. Oliphant offers his own respository of blocklists (GitHub mirror). Using an approach inspired by my tier0.csv generation process, he makes lists generated from consensus across other lists. Unlike tier0.csv, the generated lists don't have significant manual curation. Oliphant's tier-1, tier-2, and tier-3 blocklists require decreasing levels of consensus. Until recently, he also offered a "unified max" blocklist containing any entry common across at least two other blocklists every entry from any trusted source.

One of Oliphant's sources was a single-user instance with many blocks made for personal reasons: the admin was uncomfortable with topics related to sex and romance. Blocking for personal reasons on a personal instance is totally fine, but those blocks shouldn't make their way onto a list intended for others to use. The admin of this instance gave permission to use this blocklist. However, they did warn us of this fact. With my own encouragement, we decided to use their list anyway.

I had reason to be comfortable with the personal nature of this blocklist. This was was one out of 20 bias sources used for tier0.csv generation, and tier0.csv is merely a subset of the pleroma.envs.net blocklist. These two facts prevented someone else's one-off "personal" blocks from making its way onto my list. I also found that adding this trusted source only introduced a dozen generally uncontroversial entries to tier0.csv.

Unfortunately, the situation was different for Oliphant's unified-max blocklist. Several entries made that list for personal reasons. I focused too much on my tier0.csv and failed to notice that anything was off with Oliphant's lists, even though I bore much responsibility for this blunder.

{{}} from pettingzoo.co raised important issues in a thread after noticing his instance's inclusion in the unified-max blocklist. He pointed out that offering a unified-max list containing these blocks is a form of homophobia: it risks hurting sex-positive queer spaces. Simply claiming that the unified-max list isn't intended to be imported isn't enough; there's a real risk that future admins may import it without reading the documentation. I recommend giving the thread a read.

Oliphant has been getting understandable push-back for this issue in his blocklists, but it's not fair for all of the criticism to be directed at him and none at me. Many small mistakes from multiple people, including me, cascaded into one big failure.

Since then, Oliphant has removed that admin's list (and his own) from his blocklists' trusted sources. I removed the same ones. Oliphant also stopped generating the unified-max blocklist, as the potential for misuse was too great.

Supplementary blocklists

Some supplementary blocklists I maintain with very different criteria:

BirdSiteLive and bird.makeup

These are services that allow Fediverse users to follow any Twitter user. Now that far-right figures are back on Twitter, these instance pose a problem. Admins wishing to ban a single Twitter user will need to ban that user across over 100 different Twitter mirrors. Moreover, any interactions with bridged accounts are unseen by the account holder on Twitter. Twitter users may not have consented to such mirroring. Admins wishing to simply ban mass-Twitter-mirroring can import this list.

Corporate social media with user-hostile dark patterns

A short list containing instances run by social media companies that have displayed user-hostile behavior, for anybody who doesn't wish to support such practices. Privacy abuse, growth-mindsets, dark patterns, and a history of vendor lock-in are common (but not all universal) themes.

Spammy subdomains

These domains are often used for HTTP tunneling or short-lived spin-up-spin-down servers. Fediverse instances running on their subdomains almost certainly aren't in it for the long haul, and very frequently shut down within hours or days without doing a clean self-destruct. Note that this is not to be confused with traditional dynamic-DNS subdomains, which are often used for longer-lived servers (although some admins do understandably block those anyway).

This list might prove useful in non-Fediverse contexts as well; I imagine it could be useful for moderating Matrix rooms.

Receipts

The following are receipts for instances on my blocklists. Read the text surrounding a link before navigating to it, and let that context serve as a content-warning. No links point directly to the blocked instance; all go to a third-party archiving service.

Receipts are biased towards patterns in staff behavior or pervasive patterns among users with staff approval, as that generally won't be solved with a federated report. A one-off user action taken out of context, without any sign of staff endorsement, isn't enough to end up on one of these lists because it's not indicative of an instance's moderation policies. The one exception is receipts for legally risky media: I don't publish receipts for those, but it should be easy to verify them if you need to.

I use archive links instead of screenshots. Screenshots pose accessibility issues, can be doctored, and are easy to take out of context.

Toggle receipts

FediNuke entries

Criteria for a good FediNuke receipt is stricter than the aforementioned criteria:

• Reblogs are only significant if they are from a staff member and are boosting local users. They are mentioned alongside other receipts to indicate that the content in question is permitted by staff.
• Each instance must have multiple receipts.
• For larger instances: receipts must show staff behavior, or show consistent behavior from several users.

This section is a work-in-progress, and it will grow with time.

ableism and antisemitism from local user "dookie", ableist sui-bait, ableism and queerphobia. Admin often uses anti-Chinese racial slurs, more usage, other anti-asian slurs. Instance has fully open registration.

freetalklive.com

Instance "about" page self-identifies as unmoderated, except for spam. Connected to the libertarian Free Talk Live show.

kompost.cz

Racism, more racism, transphobia, queerphobia. All from admin.

occultist.space OR enjoyer.network

Run by the same admin as the.usualsuspects.lol. Admin announced the.usualsuspects.lol from the.occultist.space. See confirmation that the enjoyer.network admin is the same.

shitposter.club

Admin "Moon" posts racist bait. Blatant transphobia from user "noyoushutthefuckupdad", who's gone on multiple transphobic benders, with admin knowledge. Truscum user "animeirl", who also ran an instance of the ap-proxy block-evasion tool. User "coolboymew" rants about how misgendering and pronouns shouldn't be taken seriously because they're "politically charged". Some more racism from user "triodug". Note that its freeze-peach environment probably won't be changing: other users, including the admin, seem fond of it in this thread.

shota.house OR burger.rodeo

Instance self-identifies as a freeze peach haven that permits unrealistic/2D lolisho; this may be a legal risk, depending on your jurisdiction. Staff defends permitting bigotry while dismissing concerns about hate-speech. With that context, reporting won't address problems like racist Black fetishism from one user. Harassment risk seems low, however, and admins claim that the instance will moderate harassment but not "opinion".

lemmy.burger.rodeo is run by the same staff and has the same policies.

whinge.town OR whinge.house

Racism from staff, more racism, ableist misogyny. Both instances were set up by the same user (confirmation 1, confirmation 2), who mains on the former.

Future

Once Threads and/or Tumblr start federating, I plan to make a separate blocklist for "mainstream" social media platforms that prioritize profit over safety. I've explained my views on Threads in another post: {{}}{{}}{{}}.

The biggest complaint I've heard is the lack of reasons and receipts. I'm working on adding them to this page. {{}}{{}} is working on a separate project called {{}}{{}} to create an index of instances with receipts. It doesn't have a lot of content yet, but that will change with time. I've shared my receipt archive with him.

I like the idea of a separation between receipt-tracking projects and blocklist-generating projects. Reasons in a blocklist tend to invite retaliatory harassment in an effort to make admins hide their blocklists, often in the form of (very dubious) legal threats (defamation and privacy regulations have come up).

I also hope to see more tier-0 lists crop up. Any instance should be able to make a tier-0 list by sub-setting its own blocklist. When that happens, "Seirdy's Tier-0 list" will hopefully lose whatever authority it has.
