I have read about the community user. It is a bot that pulls old questions out, does site chores, owns unregistered users questions, protects when questions attract "me too!" answers.
But the profile page doesn't mention anything about approving and rejecting edits. How does that work? Does a bot do that, or is it a person? How does it know if it is a good edit or not?
Here is a similar question, though the answer is not really what I wanted.
