    "cid": "bafyreiabc123..."
  },

  "message": "Content has been reported successfully. Moderators will review your report.",
  "reportId": "12345",
  "reportDetails": {
    "subject": "at://did:plc:abc123/app.bsky.feed.post/spam123",

    "cid": "bafyreiabc123..."
  },
  "reasonType": "misleading",
  "reason": "Contains false medical information"
}

Reason Types ​

  • spam - unwanted promotional content, repetitive posts, scams or phishing.
  • violation - terms-of-service violations, illegal content, impersonation.
  • misleading - false information, manipulated media, deceptive practices.
  • sexual - inappropriate or unsolicited sexual content.
  • rude - harassment, bullying, hate speech, personal attacks.
  • other - anything not covered above; describe it in reason.

Error Handling ​

Validation runs before any network call:

  • A subject.uri that does not start with at:// raises a VALIDATION_ERROR.
  • A malformed subject.cid raises a VALIDATION_ERROR.
  • A reasonType outside the allowed values, or a reason over 2000 characters, raises a VALIDATION_ERROR.

Other failures (content not found, network errors) surface as the underlying AT Protocol error.
