I honestly think that anyone who moans about MNHQ, should spend a couple of months posting on other internet forums.
This is by far the fairest and most laid back forum I've ever known in terms of moderation...the only large website I've ever known where the moderators will personally engage with its posters and try to see things in context.
Trying to see things in context and be fair to everyone must be a nightmare on such a large site.
That's the reason many other sites take the easy way out and just blanket ban swearing, or have a '3 deletions and your out' rule...no matter what the reason for deletions are.
They won't always get it right, but at least they tend to hold their hands up when they don't.
