If it helps this is the query I used but I am not sure it gets everything
SELECT
p.id AS post_id,
u2.username,
topic_id
FROM posts p
JOIN users u
ON u.id = p.user_id
JOIN topics t
ON t.id = p.topic_id
JOIN users u2
ON u2.id = p.last_editor_id
WHERE (p.last_editor_id > 1 AND p.last_editor_id <> p.user_id)
AND p.self_edits > 0
AND p.deleted_at IS NULL
AND u2.trust_level > 2
AND u2.moderator = false
AND u2.admin = false
AND t.deleted_at IS NULL
AND t.archetype = 'regular'
ORDER BY p.updated_at DESC
LIMIT 500
Note that this rules out users who are staff as well as the system user, so basically the above query is just TL3 users editing around the site to tidy things up.
You could use this query as is @outofthebox in Data Explorer in the meantime…
