IMPORTANT NOTICE

The original script doesn't work on "classic" list design. It works fine on modern style design (and I don't think custom list design matters): See This

Edit: I renamed the original script to indicate that's for modern list style and added separate script for classic list style.

Where do you put this code so it can work?

You put it in here
If you are on your plan to watch section, your plan to watch will be deleted. Same goes for other tabs.

Thanks! and I was wondering if it works on the manga list too?

Currently it doesn't, but it's easy to write another script for that. Will do it later.

just change the line: animeLink.lastIndexOf("anime/") + 6, to animeLink.lastIndexOf("manga/") + 6,
and var deleteUrl = /ownlist/anime/${animeId}/delete; to var deleteUrl = /ownlist/manga/${animeId}/delete;
worked for me

I used the classic anime, and the classic manga, they worked perfectly. Arigatou!

Thank you so much, still works perfectly. Just make sure you use the correct version.
If you wanna do it on your phone, use kiwi browser.

The moronic mods on MAL are literally telling ppl not to use scripts, not to create new accounts, they're both bannable offenses. And to just suffer through it and remove everything manually because the other methods are taxing on their servers.... I'd rather switch service than waste an hour doing it manually
