I've only ever heard you say "trust us, we do this," but I can speak from experience that I have personally flagged some posts and comments that end up remaining anyway.
This is, of course, your site and you can moderate it as you please, but the quality of participation has been falling (IMO -- yes, I'm familiar with the guidelines saying not to complain about it) and it's been turning off participants who otherwise would have very wise, informed, and useful things to say.
For example, a distinguished engineer who did a lot of seminal work in performance benchmarking while at Sun and later wrote Linux's original source control system is gone now, dissuaded by the emotional and nonsensical conversations he was getting into here. IMO his opinions and insight are at the 99th percentile of in terms value here, and this site is far worse off for the absence of people like him.
Anyway, I don't want to get into a big debate here; just wanted to give my two cents.
