As I understand you can remove articles from Google search results, not from websites that posted it. Do you work with Google search engine only?
Yes we removed articles from the search results of google, not directly from the website.
If report was about copyright, first of all you have to owner or creator of content that you upload. If you're not, then I doubt that OP can help you.
Sorry OP that I intervene your topic with answer
you are absolutely right, if videos are removed by youtube then I can't help.
