I raised something here in a relevant thread recently: https://community-imdb.sprinklr.com/conversations/data-issues-policy-discussions/submissions-attempting-to-change-character-names-repeatedly-declined/62d68e6c7f73467a95edaa87?commentId=62dca07227c9e55d81c62506
For some reason @Bethanny decided to ignore me, so I'm opening a new thread.
You have a link to this Voldemort case in your guidelines as an example: https://www.imdb.com/title/tt0241527/fullcredits/
But what your guidelines say does not match what you have in that title page currently because of a recent change made to the credit.
So you should either change your guidelines, or revert that recent change that adds Voldemort character name.
