The simple logical answer to that is that it is clearly impossible to blacklist.

The more specific answer is:

git config --global user.name "Your Name Comes Here"

git config --global user.email [e-mail]

Also, looking up, you can undo a rebase with reflog, so even editing commits with an interactive rebase may not be enough to purge a git repo of identifiable information that people have entered.
