if you have sufficient proof that these repositories contain a malicious software then you should instead report them to GitHub through their contact pages (probably report abuse here: https://github.com/contact/report-content) or report the user directly from their profile like the third link: https://github.com/contact/report-abuse?report=gonzo482+%28user%29 and help get it removed from the source. (it has already happened for most of the links as they are removed from GitHub but not all.)
