Bluesky — Policy Change
Executive Summary
Bluesky opened registration to the general public, removing the invite-only requirement. Nearly 800,000 new users joined on the first day. All user profiles and posts remained publicly accessible with no private-profile feature; the AT Protocol's decentralized architecture meant data was replicated across relays and third- party services by design.
What Happened
On February 6, 2024, Bluesky removed its invite-only requirement and opened registration to the general public after one year in closed beta. The platform had accumulated over 3 million sign-ups during its invitation period and had 1.6 million monthly active users at the time of opening. Bluesky also announced plans to begin an experimental rollout of federation later that month, allowing third-party developers to host their own servers on the AT Protocol.
Who Is Affected
All Bluesky users are affected, as the platform operates on a public-by-default model where all profiles and posts are publicly accessible with no option for private profiles. The AT Protocol's decentralized architecture means user data is replicated across relays and third-party services by design. Anyone who joins the platform should understand that their content will be distributed across multiple servers beyond Bluesky's direct control.
Why It Matters
This event represents a significant expansion of a decentralized social network built on fundamentally public architecture, contrasting with traditional platforms that offer private account options. The combination of open registration and the planned federation rollout means user data will be distributed across an expanding network of independent servers. Bluesky's approach prioritizes openness and interoperability over privacy controls, which differs from conventional social media privacy models where users can restrict who sees their content.
What You Should Do
Understand that all content posted on Bluesky is public and will be replicated across multiple servers with no private profile option available. Only post information you are comfortable being permanently accessible to anyone on the internet. Review Bluesky's community guidelines and moderation features, including the upcoming stackable moderation services, to understand what controls are available for managing your experience rather than controlling who sees your content.
