Bluesky open sources its collaborative moderation tool Ozone and plans to let users run their own independent moderation services later this week
Decentralized Twitter/X rival Bluesky announced today that it's open sourcing Ozone, a tool that lets individuals and teams collaboratively review and label content on the network.

Context & Ripple Effects
Bluesky had already been building toward community-directed safety controls, first through proposed user lists and reply controls and later through automated tools and moderation lists. Ozone turns that direction into reusable infrastructure for collaborative review and labeling.
The move follows Bluesky's opening of federation, extending decentralization from hosting and network participation into the moderation layer. That makes governance design, not only protocol access, central to how the network differentiates itself.
First-order effects
Individuals and teams can use Ozone's open-source tooling to collaboratively review and label network content, rather than relying solely on Bluesky-operated moderation workflows.
The planned availability of independently run moderation services gives users and communities a path to select or operate distinct labeling services.
Second-order effects
Moderation providers and community organizers can compete on policies, expertise, and responsiveness, while Bluesky must make those services understandable and usable without fragmenting user safety.
A broader set of labels and services may give users more tailored controls, but it also increases the need for clear provenance and trust signals around moderation choices.
Third-order effects
If independent moderation services gain adoption, social-platform governance can become a contestable layer: network operators provide common infrastructure while communities and third parties supply differentiated rules and enforcement.
The model shifts the long-running moderation trade-off from a single platform policy toward interoperability, where accountability and user comprehension determine whether decentralization improves safety or merely disperses responsibility.
The trend: Bluesky is advancing governed openness in social media by separating shared network infrastructure from the services that define moderation choices.
I thought Bluesky was dead when Threads launched. I was wrong. Although Bluesky still has to close the gap in terms of audience and content discovery, open registration and hashtags will help. Most impressive IMO: Bsky has developed a competitive edge by open sourcing algorith…
Looks promising. If everything goes as the developers envisioned, this 'll democratize content moderation & empower users. But I wonder if Safety has red-teamed some of these “additional moderation services” to see how authoritarian gov might subvert these features to censor/su…
if bluesky found a way to continue using hive dot ai or whatever for gross (i.e. bulk, rough) content-level removal of the most obviously offensive and harmful stuff, that would significantly lower the human-harms cost of community moderation for unpaid mods to not have to peep s…
I think moderation is a process that is inevitably going to involve a lot of drama and problems - much like democracy. — And I'd rather have actual human users driving that inherently messy process than dead-eyed billionaire executives or their equally hideous robot-parrot prox…
I don't think I can properly convey how lengthy and vigorous the design process was for labelers & stackable moderation. Since early 2022 we've been talking about this. Then the past month of implementation felt like another two years. — It's going to take a lot more work but…

We're investing in safety from two angles. — 1. We've built our own moderation team dedicated to providing around-the-clock coverage to uphold our community guidelines.
