Yup. The tricky bit of moderation to me is dealing with well known, long term users. I find the particularly troublesome sort being people who have a good amount of contributions to their name, but a variable temper. If somebody's always a jerk that's pretty easy. The tricky bit is when it's inconsistent. Other long term community members learn what sets this person off and avoid it, and so everything seems quiet for weeks until somebody unaware hits on just the wrong subject, and this old, seemingly respected member explodes at them. This is problematic for a community. New people need to either learn to navigate this minefield, or decide that it's not worth it and leave. And a lot will definitely pick the second option. I ended up banning just a few such people and I'd say things have improved greatly as a result. Yes, there's a loss in term of contribution from very skilled people, but if a single person sours the mood for several dozen, it's not a good tradeoff. And they tend to drive away other skilled people as well, who can easily leave and be welcome must anywhere else that doesn't require them to tiptoe around that one tricky person.
