How to delete GitHub blame history?

I'd like to delete the GitHub blame history that GitHub shows (tracking all changes made)

I am aware of how to how to roll back changes, but I am not trying to roll back any changes I have made, I am simply trying to delete this history of the changes.

Obviously, I do own the repository that I will be operating on (and am the sole owner)

If this is for all files of your GitHub repository, the simplest way would be to:

• initialize a new local repository
• add files from the original repo
• add as remote the original repo GitHub URL
• force push

That is:

git clone https://github.com/me/myrepo
git init myrepo2
cd repo2
git --work-tree=../myrepo add .
git checkout @ -- .
git commit -m "Import myrepo"
git remote add origin https://github.com/me/myrepo
git push --force -u origin master
