Bluesky adds a setting to hide posts from algorithmic recommendations

What changed

On September 1, 2026 Bluesky Protocol Services described the Content Visibility Declaration, an app setting that writes a record to the user's repo asking apps to hide their posts from algorithmic recommendations. It does not need to be respected by list-based or topic-based feeds. Bluesky's Discover feed is the main example where it applies.

What it means

Posts from users who enable the setting should stay out of algorithmic feeds, which can reduce their reach in recommendation surfaces.

Who is affected

Developers of feeds and aggregators on Bluesky, and users or marketers who care about reach through recommendations.

What to do

Feed developers should read the app.bsky.actor.contentVisibilityDeclaration record and skip posts when hideFromAlgorithmicRecommendations is true. A missing record means false. The post asks for best judgment, not a hard deadline.
