Hi,
I have a use case where we need to keep track of a user who made a commit. I have couple of questions
1. Does author email in commit message is a reliable way to track users commit or should we use something else?
2. The [no reply](https://docs.github.com/en/github/setting-up-and-managing-your-github-user-account/setting-your-commit-email-address) email provided by github does bitbucket has something similar?
3. What happens if a commit doesn't contain author email? What percentage of user do not use any email id in their commit message.
