We explicitly do not allow indexing on shared public links. We don’t want to poison Google.
To unshare click here:
Deleting a message does not nuke the share at the moment. I am torn on this one.
To work around and find all these orphans you can use this data explorer query:
SELECT
shared_ai_conversations.*
FROM
shared_ai_conversations
JOIN
topics ON shared_ai_conversations.target_id = topics.id AND shared_ai_conversations.target_type = 'Topic'
WHERE
topics.deleted_at IS NOT NULL
