A git pre-push hook to prevent pushing commits made with a specific author to remote repositories.
Add to your git config with the host and allowed email address:
[ghostwriter "git.bigcorp.com"]
email = bob@bigcorp.com
[ghostwriter "github.com"]
email = bob@example.com
The above will prevent pushes to git.bigcorp.com if any of the commits were not authored by bob@bigcorp.com.
You will need to symlink the build artifact into your repositories .git/hooks directory as pre-push
When pushing you will see something like this:
$ git push
verifying commits to git.bigcorp.com are by Bob with email bob@bigcorp.com
rejecting push due to commits with wrong author:

error: failed to push some refs to 'https://bob@git.bigcorp.com/bob/WidgetService.git'
Yes, its probably overkill, but it was more fun than writing a shell script.
