Yahoo has a written description about spam and other inappropriate content that should be removed from its search engine index. Their Quality Guidelines state that "pages that have substantially the same content as other pages" should not be included in Yahoo's index. You can report plagiarism using their spam report form.
If you're really serious and believe that someone has infringed your copyright, you can report this in accordance with Yahoo's Copyright and Intellectual Property Policy.
