So, I’m a developer. I am following along with and reading this thread:
https://oisaur.com/@renchap/116056634129526611
All I can think while reading this is: Well, that’s unfortunate.
So, one of the very popular features on Bluesky—also popular on Twitter—is the ability to select who can reply to a post. A major issue in the Fediverse is the inability to decide who can reply, and once you block someone, their harassing reply is still there. I honestly thought it was simply a case of them choosing not to add or address it for cultural reasons. What is clear from that thread is that they were always aware that the ActivityPub protocol and most Fediverse implementations don’t provide a universal way to control reply visibility or enforce blocks across instances. They were hedging and hiding behind cultural norms this whole time instead of working to fix it, because they were too busy waging political culture wars instead of doing their damn jobs.
That realization sunk my hopes. It basically means that the social media ecosystem with the most moderation tools is Bluesky and the ATmosphere, albeit Bluesky isn’t fully using all of them and is using the moderation tools in ways that selectively moderate according to their enigmatic interests. That does not make me feel good. Honestly, that makes me feel fucking awful about the future of the Internet.
ActivityStreams/ActivityPub was formalized around 2018, and platforms like Mastodon (which implement the ActivityPub protocol) have had years to work on federation and moderation tooling. Instead, many of those years were spent debating culture and writing manifestos. The most disturbing thing about all of this is that it had so much potential. But yeah, I think the Fediverse is going to be relegated to a legacy platform like Usenet or IRC. It’s not fixable, and the folks over at the Fediverse have alienated so many developers that no one really wants to work on fixing it.
The co-authors of ActivityPub are working on other social media projects that have nothing to do with the fediverse. Meanwhile, Mastodon’s founder, Eugen Rochko, stepped down as CEO in November 2025 as part of Mastodon’s transition to a nonprofit governance structure. The restructuring was intended to formalize governance and reduce reliance on a single individual. Rochko transferred control of Mastodon’s core assets and trademark to the nonprofit organization and remains involved in a strategic and advisory capacity. Day-to-day operations are now overseen by an executive director under a board-governed structure. I believe how badly Eugen fucked Mastodon is a large reason why he stepped down, albeit they are all doing the virtue signaling thing.
For the most part, I have pretty much pulled away from microblogging platforms as a whole. I was never a heavy user of anything but forums, and I was part of the occult niche. Since that is pretty much gone, there really isn’t a reason for me to be on social media, which is why I mostly blog. It really sucks because I wanted to believe in ActivityPub and the fediverse.
It pretty much comes down to the fact that the ActivityPub protocol is flawed at the protocol level when it comes to protecting people from harassment. While Bluesky’s app view is choosing to apply its tools selectively to address this, it is more capable of protecting people. Honestly, that really sucks, because that spells the death of this protocol. ActivityPub’s decentralized design doesn’t provide built-in, enforceable protections against harassment. This makes moderation and harassment mitigation practically impossible.
Renaud Chaput so much as admits it here:
“So we need to consider if we want to switch to a “thread context”-based approval model, there the author of the root of the thread controls all the tree of replies. Which would be a big change for Mastodon (and similar implementations), but might be more aligned with what user want, and solve other issues as well (replies federation).
But that would be a huge undertaking, with lot of problems related to backward compatibility (for example)”
What I noticed was this phrase by Renaud Chaput:
“First step for us is probably staying alive and continuing having a team that is focused on building a better product, which is our focus right now. We are very well aware of this topic (as I keep repeating each time you mention me 😉 ).”
They are saying the quiet part out loud: We are having issues staying relevant.
ActivityPub is built on the ActivityStreams 2.0 vocabulary. Three core components define it: Actor, Object, and Activity. It provides a Client-to-Server (C2S) API that lets an Actor submit Activities to an outbox. It also provides a Server-to-Server (S2S) federation protocol. This protocol delivers those Activities to other servers’ inboxes.
Replies are created by setting the inReplyTo property on an Object. Servers may expose a replies Collection. However, that collection is optional and not globally authoritative. The specification describes how Activities are serialized and delivered. It does not introduce a canonical container for conversations. It does not define a required global index or binding enforcement rules for moderation. A Block Activity is defined as a type of Activity. However, remote servers are not obligated to remove or hide content beyond their own policies. Each server maintains its own inboxes, outboxes, collections, and storage model. It interprets incoming Activities according to local implementation choices.
This facilitates interoperability at the transport and vocabulary level. It does not do so at the level of governance. Servers do not have to construct identical conversation graphs from inReplyTo chains. Nothing in the protocol allows an Actor to assert authoritative control over all descendant replies. This is the main problem. Federation operates peer to peer among autonomous servers. Moderation decisions, including defederation, filtering, and suspensions, remain local. The specification does not define a global control layer.
The AT Protocol approaches the problem differently. Users are identified through Decentralized Identifiers (DIDs). They publish signed records stored in repositories. These repositories are usually hosted on a Personal Data Server (PDS). They are append-only and cryptographically verifiable. Records follow schemas defined in Lexicon. Lexicon describes types, fields, and RPC interfaces in machine-readable form. Updates propagate through relays. These relays aggregate repository changes into a network-wide event stream, often called the firehose. Higher-level services, including AppViews, subscribe to this stream. They may also query indexes derived from it. The AT Protocol defines message delivery, identity, storage, and synchronization.
Within the AT Protocol, moderation operates across the same repository data. Labeling and visibility controls are expressed as structured records. Clients or AppViews can apply them deterministically if they choose to consume them. Content exists as signed records keyed by DIDs. It is distributed through relays. Moderation services therefore work against a consistent dataset rather than isolated server copies. Identity portability follows from this structure. Users can move between hosting providers without losing their DID, repository history, or social graph.
ActivityPub standardizes how Activities move between servers and how they are described. It leaves indexing, thread authority, and enforcement to individual implementations. The AT Protocol defines repository structure, identity binding, record schemas, and synchronization across the network. ActivityPub centers on federated message exchange with local policy control. No participant has protocol-level authority over the shape or visibility of a conversation once it federates. The AT Protocol centers on a shared record system with portable identity and network-wide data propagation. Moderation and visibility decisions can attach to the same canonical records seen across the network.
In ActivityPub’s model, moderation is local. If someone replies to you in a harassing way, your server can hide it, block it, or defederate from the offending server. Other servers may still store, display, and propagate those replies according to their own policies. There is no protocol-level mechanism that lets you assert binding control over how replies to your post are indexed or rendered elsewhere. Harassment mitigation is fragmented. Harassment can persist in parallel contexts even after you act against it locally.
In the AT Protocol model, content exists as signed records in repositories keyed to portable identities. It is distributed through a shared data propagation layer. Because of this, moderation services can operate against a consistent dataset. Labels, visibility controls, or account-level actions can attach to the same canonical records that other services consume. While it does not eliminate harassment, it makes it technically possible for moderation decisions to propagate more coherently across applications that choose to honor them.
So the difference for harassment is this: in ActivityPub, protection is inherently piecemeal and server-scoped. In the AT Protocol, protection can be structurally network-aware. Identity, storage, and moderation signals live in the same shared data model.
Basically, the fediverse has no means to keep vulnerable, marginalized people safe. The AT Protocol does, albeit the Bluesky app view chooses not to use it. The point is that it has the potential. The last time I tried to explain all of this, I was harassed by a person who operates multiple servers and accounts on here:
@FediThing @FediTips @FediFollows@social.growyourown.services @FediVideo@social.growyourown.services @FediGarden@social.growyourown.services and @homegrown@social.growyourown.services
The protocol is fundamentally flawed, and they do not know how to fix it. These people are incapable of good-faith conversations, so I am avoiding tagging them or attaching this response.to the thread, because their response is basically to stall, hedge, and gas light.
I’m not a fan of Bluesky — not at all. I really wanted to love ActivityPub, but I think Eugene pretty much killed it within the last three years. They had a very narrow, myopic culture and vision in mind, where they completely ignored all criticisms. Now, there is really no way to fix this mess, which is why they stick to gaslighting their users and literally harassing any developer who criticizes them. Social media has normalized lying to its users, so am I surprised?
Edit:
What a surprise. An anti-black reaction that pulls the it is okay to ignore you because you are an angry black person. Yes, black people are angry, and that you do not understand why is the problem.
I’m not going to go back and forth with a racist, nor am I going to quote them because of my stance on spreading misinformation and vitriol. A person who was implicated in the anti-Black behavior of the fediverse tried to discredit me as a Black person by claiming that I am not on Blacksky, have not worked on Blacksky, and am not happy or positive enough to be included in the Black folks who have been harmed by anti-Blackness.
Yes, they said that with a straight face. Blacksky exists because Black people were angry at being mistreated by the fediverse. Ergo, since I am not happy about being mistreated, I can’t be part of that demographic of Black folks. They are tacitly expecting trustworthy Black people to respond to abuse by being happy. What kind of Jim Crow shit is this? Therefore, it is acceptable to dismiss my experiences as a Black person because I don’t conform to the stereotype of what a Black person in America is.
In other words, they are saying I am a hostile angry black person, and we can disregard what I have to say because I am an angry Black person in Donald Trump’s America.
What kills me is that these folks have no insight into their own racism. This is all the attention they get, because I believe racists should be isolated among other things. They truly believe they are the good guys and that the savior complex is an imperialistic colonial archetype flies over their heads I don’t think white racists can ever change, so I will not be addressing them. That’s all I will say about that.
Edit again:
Welp, after seeing the first edit, the hit racist dog deleted the top level of the thread about me. That is what is called a consciousness of guilt, because if they had genuine good intentions and truly believed what they said was right, they would have said it with their whole chest and would not have deleted the top thread reply. Also, the little group of Fediverse racists explicitly rushed to report me. Report me to who—myself? It’s my instance. I have not explicitly violated any rules of this person’s home instance, but they feel entitled to try and have me removed from the Fediverse because I did not respond to their triangulation, brigading, and harassment by being nice. I did not take the mistreatment with a smile and a nod. Racist white people can fuck all the way off.
