I thought of contacting Thunderbean on that. Then someone on MySpleen suggested that it should be done by someone who bought the disc. Class316, maybe the original uploader on Cartoon Chaos did?
Somehow it’s an anonymous upload. But I can post something on the comments. What should be said exactly?
Another option would be talking to Thunderbean directly via this thread: https://forum.blu-ray.com/showthread.php?t=226492&page=485
