Can Someone See Who You Blocked on Bluesky? Yes. Here’s How to Check

Description and use

Bluesky users can verify the public visibility of their block actions by querying their PDS with curl and jq or via pdsls.dev.

Problem

Users want to know if their block actions on Bluesky are publicly visible and how to inspect their own data.

Outcome

The workflow demonstrates that block data is publicly accessible; users can audit their own data and decide whether to mute instead of block for privacy.

Workflow

• Resolve handle to DID using com.atproto.identity.resolveHandle
• Determine PDS endpoint via plc.directory
• Describe repo to list collections with com.atproto.repo.describeRepo
• List block records with com.atproto.repo.listRecords for collection app.bsky.graph.block
• Optionally download entire repo with com.atproto.sync.getRepo
• Use pdsls.dev to browse collections in a browser

Evidence

Every account you've blocked on Bluesky is sitting in a public JSON endpoint.

Source
