How do I prevent commits from being removed from github?

Question

See title. Worst case, is there a way I can track the history of commit removals?

Answer 1

Add to Branch protection rules

Define branch protection rules to disable force pushing, prevent branches from being deleted, and optionally require status checks before merging. New to branch protection rules?

Going to your repo settings -> branches -> add rule

Configuring protected branches

Defining the mergeability of pull requests

Answer 2

Like Tim Biegeleisen said, the best way to do this is to restrict push access to your repository, and only let people contribute to your repository through pull requests (which you can then monitor).
