I’ve slipped your post over to this topic to group the requests together.
This also cropped up elsewhere too recently and I created a small data explorer query so at least admins(/groups who were granted access) could have a ‘look-up’:
-- [params]
-- topic_id :topic_id
SELECT target_topic_id,
acting_user_id,
created_at::date
FROM user_actions
WHERE target_topic_id = :topic_id
AND action_type = 15
ORDER BY created_at DESC
It’s not exactly what the feature request is aiming for, but may help in some cases.
