Does anyone know how to delete a forked GitHub repo that's been subject to a DMCA takedown? The repo is there (with a DMCA banner) but I can't do anything to it. I've tried clicking the 'settings' tab but nothing happens.
You can not delete that repository on your own. I also had a fork that's been subject to a DMCA takedown. I sent a mail to GitHub Contact and requested to delete that repository. After 2 days, the repository was deleted.
You can also check the GitHub article on DMCA Takedown Policy.
