I found this out when I was migrating code from hg in google code (now archived) to github. The source commits didn't have valid email addresses so they didn't work very well with git and github, so I just rewrote them to something else. There's no special checks that a commit came from the owner of an email address, and there's no way to prove it did/didn't. Take commit metadata with a grain of salt.
