Personally, I think the people who never got to experience Chatsubo should consider themselves blessed to have a forum that's moderated at all.
It is also a perfectly reasonable yardstick for measurement because Chatsubo is the reason Backstage exists. Chatsubo's team took a much more laissez-faire approach to moderation in the time I spent there, and the increasingly hostile and vitriolic atmosphere it helped create there (and elsewhere, thanks to the arguments spreading like herpes into places like OOC, and LM OOC, which is now Red's District) chased people out in droves. Did it have its good days? Yes, it did. But the bad days could get so bad in comparison that it was like shooting a kid's parents in front of him, and then giving him a lollipop as if it would make it better.
Pretty much nothing was moderated there outside of the sorts of things that would earn someone an instant ban from OOC/Summit, and the response was to try an experiment where many of the things that made Chatsubo an increasingly unpleasant experience for many people, were not tolerated. Not that it's the best metric in the world, but the fact that a number of Chatsubo's old/current moderation staff and bigger posters come here and are actively contributing, indicates to me that the experiment has worked. Obviously those people may have different opinions or views of how things were over there - they're welcome to them and are free to provide their own, but that is what I took away from my time reading and posting there.
Furthermore, it doesn't really matter whether people are trying to use moderation to "win" arguments, or if they're being "oversensitive": if the reported post is pretty clearly not a violation of the rules, we're going to ignore it once we've finished bashing our heads against our desks in such a coordinated manner that we would make Olympic synchronised swimming teams look like a bunch of amateurs. Normally these sorts of reports are spread apart. It's only when they start piling up in a short timeframe, as they have in the last two weeks or so, that we actually stand up, say "hold on a fucking minute," and do anything about it.
In this case, after some discussion on a couple of the automatically-generated report threads, Casi elected to make a public post about it rather than one or several of us contacting the offenders privately and individually - given there were several people contributing to the growing face-shaped dents in our desks, it was more efficient, and it served the purpose of also providing a reminder to everyone else not to do the same.
We try to take every report seriously, but it's really hard to do that when people start using the system to win arguments. Crying wolf and whatnot.
