Sorry I meant TL2

    SELECT u.id user_id, current_timestamp granted_at
    FROM users u
    WHERE u.id IN (
      SELECT invited_by_id
      FROM invites i
      JOIN users u2 ON u2.id = i.user_id
      WHERE i.deleted_at IS NULL AND u2.active AND u2.trust_level >= 2 AND not u2.blocked
      GROUP BY invited_by_id
      HAVING COUNT(*) > 3
    ) AND u.active AND NOT u.blocked AND u.id > 0 AND
      (:backfill OR u.id IN (:user_ids) )

Its meant to be a reasonably hard to get badge
