But what I worry about is that it may presume that the staff themselves already operate in (your interpretation of) good faith, and I don't think that is always the case.
What is a user's recourse when they disagree with the mods? And what says they will comply with any decision reached from said recourse?
You could say "we must allow disagreements", but at some point this becomes a paradox of tolerance and then you risk it devolving into pointless arguments on either side.
I think the whole "good faith" part could only be enforced by a universally trusted party, like maybe a robot. But even then, people will disagree about how it operates... so maybe this problem is impossible to solve.
