Are the boards over-moderated?
As far as I can tell they seem to be at the same high standard and level that they've always have, or rather I should say the same high standard as they've been since I discovered and joined the site. Are there more thread moves currently then say last month? Possibly, but that's not the fault of the moderators. Are more threads getting redacted or changed then last month? Again it is a possibility, but everything I've seen that has gotten changed by a mod was due to either copyrighted stuff was posted, unreadable grammar/spelling/everything in caps, or because someone made a double post instead of a modify. As for the preponderance of 'thread moved' stubbs, yeah they do kinda clog a front page from time to time, but it's better that they exist rather than not, and it's also not that hard to move past the front page should the need arise (although that probably isn't too necessary as the ever popular Eldar board still has posts whose last input was the first of last month)
Are there people out there that are ignoring proper nettiquite and site rules? Yes, that's why there are moderators. Are there more offenders then say last month? Again there is a possibility of it, but I lack the variables or the desire to try and rate it. Nevertheless I'd wager that the boards aren't being over-moderated, if for no other reason then I've never seen a mod go crazy and change someone's complete post, or move something to the completely 'why the heck is it there' level (such as putting an Eldar army list into the painting forum because there was mention of paint in the post... I really hope that never happened I'm just creating an example out of thin air). Also I've never seen anyone make a brief offtopic comment and get it mod-ed out. But when it's say a paragraph or more on something completely offtopic showing no remorse or even the attempt to integrate it into the topic at hand, or worse an entire post of nothing that's contributing to the topic at hand, that's when you need a mod to wrist slap or even split the posts. And even then it's something I've only seen rarely. Just because I didn't see something doesn't mean it doesn't exist, but if you too closely follow that logic, Mothman and the Jersey Devil must exist because I didn't see them.
The last thing I'll say is that if you've ever sent a message or had an in forum discussion with a mod, they're generally all dedicated to making the site the best it can be. I'd like to say all, but I try and avoid absolutes, especially when I'm sure there's mods I've never seen/heard of because I don't read every section of the forum. Nevertheless it's quite clear to me that the mods are doing their jobs to the best of their ability as a public service to us all. More than just that, they are incredibly open to input, perfectly evidenced by this thread, and are all open to investigating their own practices to ensure that they can maintain a high standard of performance. If they didn't care, they probably could have deleted this subject.
