I’m cleaning up an old abandoned forum…
It has over 60,000 members but few are real users and have written posts.
Is there a way to delete all users who have not written posts?
Chatgpt wrote me this script and it seems to have worked but if anyone has another safer and tested method I prefer it.
Thanks

DELETE u, um
FROM wp_users u
LEFT JOIN wp_usermeta um ON u.ID = um.user_id
LEFT JOIN wp_posts p ON u.ID = p.post_author AND p.post_type IN ('topic', 'reply')
WHERE p.ID IS NULL;
