I would like to give an update on "federation" on Bluesky.
-
@mattsheffield The pds doesn't view posts. The appview views posts. You need like five separate components in order to look at a post on Bluesky and every single one of them introduces the potential for censorship. I can't read the site through pdsls that's bonkers
@mcc The layers are indeed censorship choke points.
What I'm saying is that in this case, it appears to be the labeler of Bluesky that's the issue. Any app view that uses it will suppress Link's parts, even if he's not banned locally.
The app view of Blacksky would hide him locally but he wouldn't be banned. This is why he can post but can't see his own posts. The Blacksky app view (the site) is independent except for the labeling.

@tess But
1. Even if Blacksky's appview is limited to the last seven days, or limited only to information Blacksky controls (eg the blacksky pds), I should still be able to see Link's posts, or Link's last seven days of posts. So it seems blacksky's appview isn't being used at all.
2. The test linked above, too, seems to imply I am using Bluesky's appview in all cases.
@mcc that all scans, and, I hope it's just a miscommunication as to the current state of BlackSky.
If nothing else, this is the five-alarm fire that should expedite the switchover.

@tess I am inclined to give Rudy a lot of leeway because he is clearly moving very fast. I'd rather him engineer than answer my questions and I'd rather not interrupt him while he's engineering a thing I want to use.
But I just want to know what the software I'm using… like… is.

@mcc *sigh* i get it
I'm holding out for Northsky even though I fear it's going to be the typical flameout but the fact that BlackSky is offering PDSes to people outside the community is also super appealing.
Seeing how they handle this situation might be what puts me over the edge.
That said, I'm also not trying to build my own tools; just use a nice platform run by people I trust.

@mattsheffield *sighs*
I feel like I'm having a lot of repetitive conversations. The thing you are claiming was my conclusion as of last night, but then I was shown an additional piece of evidence, which makes me conclude something different. This was documented in one of the threads I link above, but I link a lot of things above, so I assume you didn't see it. I can explain it, but it would make more sense to just wait for Rudy (who I've asked for an explanation) to explain.

@mcc I think I did see it, the one referencing the network traffic from bsky.app? I think that's because the labeling instructions are pulled from there and assembled by the client. So it appears to be an app view issue but is actually a labeling one.
But you're right that only Rudy can clarify this

@mattsheffield In the screenshot, you see two headers: atproto-accept-labelers, which shows two labelers i assume to be bluesky and blacksky, and atproto-proxy, which indicates which appview is to be used (source: bryan newbold from bluesky), and shows only api.bluesky. So I believe both issues are live. But I am more worried about the appview/atproto-proxy issue, because out of the two, I assume it to be the more difficult issue to fix.

@mcc It's possible that Rudy has an independent app view because that can be part of a PDS, but he is not deploying it because his users wouldn't be able to use a mobile app to interface with.
They tout the ability to log in via the Bluesky app into Blacksky PDS, and possibly this is why that traffic is happening.
I have seen Link's account on another PDS, which does suggest that the app view and labeler are both live issues, as you're surmising. https://social.shatteredsky.net/profile/did:plc:63hvnyjvqi2nzzcsjgnry5we

@mattsheffield I do not think, in the context of the post you have made here, shatteredsky is "a PDS". I think we are using terminology differently and this is making it difficult for me to follow the conversation.

@mcc It is both a PDS and an app view. I'll be publishing a piece about this later today after getting more info. Nothing from Rudy though

So. The thread above. An update.
We finally got a live test of the "Gertrude scenario", when a popular Blacksky user got permbanned by Bluesky. I, using my own PDS and blacksky's website, can't see him or his posts ( https://blacksky.community/profile/did:plc:2aebn3xk5t63net43eeepire/post/3m2iokicegs2b ). What gives?
A lot of people claim this is because Blacksky really is using Bluesky's appview, and gave me a way to verify this looking at headers. This seems to contradict Rudy's previous claims. I've asked Rudy for clarification: https://bsky.app/profile/did:plc:2aebn3xk5t63net43eeepire/post/3m2jve23cf22m
@mcc@mastodon.social amazing thread. so clear even explaining what you’re not clear about. but it does make me feel like it shouldn’t be this complicated. i haven’t looked at atproto but everything i read makes me not want to.

@ellyxir I honestly don't think their architecture is very good
-
@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)
@mcc mmmmkay it looks like Rudy is now in the process of "standing up an app.bsky.* API server" (aka appview) which "Is different from our community.blacksky.* API which is going on hold". So, my best guess is that his answer to you reflected the architecture (where the ommunity.blacksky,* API server is conceptually part of blacksky,.community) rather than the currently-available public implementation at the time.
(And no idea whether he's standing up an early implementation of their Rust appview or doing the off-the-shelf Bluesky appview or something else.)

@jdp23 What's interesting to me here is, the bluesky line is "ha ha it's super good everyone is angry at us because it accelerates federation", but you're making it sound like Rudy is having to upend his software engineering schedule to do stuff he otherwise wouldn't have had to do at all early, because of this incident forcing him to protect his users
-
@mcc what exactly is the benefit of migrating to a non bluesky PDS? I understand being on an entirely different vertical stack like Blacksky or Northsky but what does being on a PDS give you? Aren't you still (almost) entirely at bluesky's mercy?

@mcc @jdp23 here guys this might help clarify why Rudy has to rearrange his epics in jira:

moderation can only be additive until/unless you pony up the CSAM/hashmatch API key money plus roll and run yr own mod sys at scale. thats the real Achilles heel of composable moderation-- replacing the bottom layer is incredibly expensive -
@anna @adrienne @eniko @mcc all the records in your PDS contain references to your identity (DID document), it's theoretically possible to modify the data to change that but requires rewriting your entire PDS for that account, so not particularly practical.
It's the DID that is moderated against in the higher layers, not your handle.
So it doesn't matter if you're @fred.example or @jason.example, if the DID used for one becomes the DID used for another handle.
It's kinda like how on ActivityPub, software has often encoded your username into the identifier for all your posts, meaning you can't change it without breaking everything.
(Though Mastodon is starting to fix this long-standing issue, there's fix only applies on new accounts, there's no protocol level way to fix it yet — it's kinda a weakness in JSON-LD)
