I don;t think bringing this to the boards is a mistake because it raises awareness about what standard are being enforced.
Is there nowhere that it says, "Arguing with a mod on public channel ingame is an instant mute" other than in these threads? There should be.
Beyond that, at the end of the day depending on how long Moly was on about it on 200, it might fall under the "don't be a dick on channel" common sense clause. But, we all know some people need the line drawn explicitly in sharpie, crayon, and highlighter before they consider the rule properly explained.
