Thanks for your response, and I agree. The rare inconvience of reverting a change that someone put in abusing the system is far less then the annoyance of having to wait for a minor change to complete the review or waiting for reviewers to approve as I make a minor change.

I had a similar error when initially trying to clone via ssh, "sudo: a password is required". For us, our repos hosted by phabricator were owned by root instead of the phabricator daemon. A chown of those repos on the server provided a quick bandaid. I can't remeber what the actual solution was, though. I'll ask around.
