I would like to give an update on "federation" on Bluesky.
-
@mcc Content doesn’t get removed from the PDS it would be hidden by labels - accounts do have takedown labels applied.
Bluesky operated relay doesn’t censor Lexicons that don’t validate and it doesn’t enforce moderation.
For those following along at home the relay costs about $30/month to run for all ~38M accounts worth of content.
@boris "Content doesn’t get removed from the PDS it would be hidden by labels - accounts do have takedown labels applied." I could be wrong but this seems to be contradicted by actual events over the last two weeks.
"Bluesky operated relay doesn’t censor Lexicons that don’t validate" Contradicted by my own testing. Either the relay censors them or the appview does and it comes to the same thing, because when I make 301-character posts even third party tools can't see them.

@mcc am having a discussion of this on bsky that is helping to disambiguate :
https://bsky.app/profile/futur.blue/post/3lyuzwzb2k226
also https://github.com/zeppelin-social/bluesky-appview@fleeky As an update, I searched on blacksky.community for "from:me blackbird" and found a post from 2024. So they have some source of older posts.

@mcc accounts get taken down! Posts do not / individual posts doesn’t get removed out of the repo (would also break verification of a repo and is detectable)
yes apps all choose their validation (and for that matter strong types). Regardless it’s not the relay that’s doing it if you’d like to be correct about where locus of control is.

@boris "(would also break verification of a repo and is detectable)"
What happens if I delete a post from a repo? If it can't be removed can someone then query the post from my PDS direct and get a copy of the deleted content?
-
So what I understand from this is that it would be relatively possible for BlackSky or NorthSky to add ActivityPub as a secondary protocol in ways that would likely be unfeasible to do the other way (ActivityPub instance using ATProto as a secondary protocol)

@mcc it seems like with enough effort some amount of mastodon sparsity could be implemented in bsky ,, so my current criticism still stands , i still think mastodon is easier and cheaper to maintain but bsky is definitely more popular (if you like that sort of thing) and could be cludged into different network architectures probably with enough effort .. main question is which way will it evolve ?

@mcc Bsky doesn’t have auth on your account and can’t delete individual posts.
The user can delete posts as they like and then it’s truly deleted and can’t be queried.

@mcc Blocks are "enforced" at the client level. I know, I know, that probably merits another "oh dear" but that's how Bluesky is doing it. So blacksky.community as a client doesn't do age verification for DMs in the UK, or block access to Mississippi.
Takedowns by contrast are at the AppView and someties PDS level.
@jdp23 Rudy says they're appview and also client. https://bsky.app/profile/rude1.blacksky.team/post/3lyvbqh3m3s2e

As an update since posting the above thread I have received replies from two people, one saying I am underestimating the level of stack coverage Blacksky has, another saying I am overestimating it. Also a "AppView" and "Client" are different. Sorry.
The stack is just so tall! There are *so many* layers in this protocol's model. And it seems like every single one of them is an opportunity to introduce censorship
Update: Rudy who operates blacksky.community responded to this thread on bluesky. Above I said I wasn't clear on how independent Blacksky was of the Bluesky infra. His answer is "completely". They run their own relay (which scrapes PDSes itself), the relay feeds into their own appview, the appview feeds into their own client. https://bsky.app/profile/rude1.blacksky.team/post/3lyv5rwpc722c
And since they bridge end-to-end, in my Hypothetical Example above, they *could* choose to make different moderation decisions from Bluesky PBC.

@mcc so I saw! I responded over there. I was in a video disucssion on Friday and I could have sworn he said that the appview wasn't released yet, but it looks like I was just confused. If so, sorry for the misinformation!

@jdp23 Blacksky is not only hosting a Bluesky alternative, they are *coding* a Bluesky alternative (in Rust, where Bluesky prefers a combination of TypeScript and Go). I assume(?) the combination of Rudy's statements should be interpreted to mean that the self-authored AppView is not ready yet, so he is hosting a PDS he wrote, hosting a relay he wrote, hosting Bluesky's appview and client on top of that, and he intends to replace Bluesky's appview soon. I assume.

@mcc excellent, good to know!

@mcc it's certainly possible! I didn't think they were running a separate appview yet but I could easily be wrong.
(blacksky.community is currently a fork of the Blluesky app-aka-client, it hasn't diverged much yet. not sure if and when they're planning on writing their own implementation of that)

@boris @mcc PDS takedowns are happening though: https://bsky.app/profile/pfrazee.com/post/3lyt3yumpos2q
This is stronger than a label, isn't it?
Maybe not the same technically as content being removed from a PDS, but if the whole PDS is taken down that's functionally equivalent.
-
@makeworld All I know is I see reports over the last week of posts just disappearing. This seems(?) to be a new event borne of the moderation staff finding too much content they feel they should moderate and panicking. If I were on a bluesky pds right now I'd be getting out before it happened to me.
@mcc I agree with you and I'm working on migrating. I don't see how this relates to my post though. I'm trying to compare the downsides of ATProto you raised with how ActivityPub would perform.

Oh, it doesn't! I was trying to do a "I don't think I can intelligently comment on that, here are the only things I can say for sure"

@makeworld @mcc it’s all labels
Boris (@bmann.ca)
These are labels applied to posts, yes? !takedown is the one I always forget / don't have a good reference for since it's not on this page as a "global" label https://docs.bsky.app/docs/advanced-guides/moderation Is that an account level takedown or a post level takedown?

@boris what about "Takedowns on accounts and records apply on the API level regardless of the labeler headers."?
Paul Frazee (@pfrazee.com)
Okay I got some answers. Takedowns on accounts apply on the PDS level. Takedowns on accounts and records apply on the API level regardless of the labeler headers. I’ll explain why and share some thoughts in next posts

It really sounds like user data/content is being made inaccessible at the source, but I'm out of my depth here.

@boris "Bsky doesn’t have auth on your account and can’t delete individual posts."
This is true in my case because I self host a PDS. Most users use a Bluesky PBC hosted PDS. In this case, Bluesky owns everything, they have the keys, the bits are resident on their servers. What prevents them from deleting a post? Aren't they legally bound to delete posts in case of DMCA takedown, CSAM, etc?
