When valid credits, on a film or show, get submitted and accepted and added to the film/show's page, it either adds those credits to the page for the cast and crew listed, if they have a page or creates a new page for them, if they don't currently have one. The site does not need you to add your own page.
If the credits are valid, there is no way to remove the page. A page can only be removed by staff and they won't do so if the information is valid.
