I haven't. So what? Is there anything I'm wrong about in a way that you could provide meaningful evidence on? Surely you aren't arguing that only moderators are qualified to weigh in on the social value of moderators - this sort of logic wouldn't pass the laugh test if we were talking about police, or soliders, or middle managers, or low-level government bureaucrats. This whole "thin blue line"-style thinking that moderators are flirting with here is... cringey.
