If you work on Open Source Software chances are that you are exposing your personal or work e-mail address to the public.
If you clone any public repo and you run
git log inside of its folder
you get a list of commits which includes the e-mail addresses of the authors.
Don't get me wrong this is not a bug.
However, I don't know about you but, I am not comfortable with sharing my personal e-mail address with the entire World.
Then hide it!
GitHub has a feature to keep your e-mail address private and prevent it to show up in their website.
If you are worried about spam or have other privacy concerns you can always use a private GitHub address instead.
You can use the email address <username>@users.noreply.github.com for all operations supported by GitHub Flow in the browser.
Basically do the following from your terminal:
git config --global user.email "firstname.lastname@example.org"
username with your actual GitHub username.
As a consequence of this operation your e-mail address
email@example.com in the git history too.
Fixing old commits
Keep in mind that the suggested changes will only affect new commits.
If you want to patch the entiry history of a repo GitHub has a simple tutorial that explains how to do so.
PRs and misc
I am not sure if you can patch Pull Requests to repositories of other people or orgs.
It might be possible to submit a PR with the fix but the repo
owner should be cool with you pushing with
--force I guess.
