@ -33,15 +33,13 @@ I maintain three main blocklists for the Fediverse:
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. {{<mention-work itemtype="BlogPosting">}}{{<indieweb-person name="Oliphant" url="https://oliphant.social/@Oliphant" itemprop="author">}} describes them in his article {{<cited-work name="The Blocklist Algorithm" extraName="headline" url="https://writer.oliphant.social/oliphant/the-blocklist-algorithm">}}.{{</mention-work>}}
This post is an attempt to document how they are made, their differences, their intended use, and especially their caveats. It also contains a work-in-progress list of receipts for instances in FediNuke and my Tier-0.

## How Tier-0 and FediNuke work
[My tier-0 list](https://seirdy.one/pb/tier0.csv) (mirrored to `tier0.csv` in [the Oliphant repository](https://codeberg.org/oliphant/blocklists)) is a subset of the `pleroma.envs.net` blocklist. It contains entries that appeared on at least **15 out of 28** 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](https://seirdy.one/pb/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 15 instead of 14.

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](https://writer.oliphant.social/oliphant/the-blocklist-algorithm) use my blocklists as sources, and are powered by FediBlockHole.
2. Other 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.

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 {{<indieweb-person name="Oliphant" url="https://oliphant.social/@Oliphant" itemprop="mentions">}} when generating lists; we share ideas regularly. Oliphant offers [his own respository of blocklists](https://codeberg.org/oliphant/blocklists) ([GitHub mirror](https://github.com/sgrigson/oliphant)). 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~~ <ins datetime="2023-05-02T08:38:00-07:00">every entry from any trusted source</ins>.

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.**
@ -151,9 +149,9 @@ Unfortunately, the situation was different for Oliphant's unified-max blocklist.
{{<indieweb-person name="Tyr" url="https://pettingzoo.co/@tyr" itemprop="mentions">}} from pettingzoo.co [raised important issues in a thread](https://pettingzoo.co/@tyr/110289010380366104) 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.

Oliphant also stopped generating the unified-max blocklist, as the potential for misuse was too great. I became less involved in Oliphant's list; by the end of August 2023, I decided to withdraw as a source for it as soon as a hard-fork takes off.
