In the real sense of that expression, your first sentence as quoted should be enough reason to diffuse any doubt around having a self-moderated thread. Sadly, your last sentence is often why most users self moderate. It hurts when one finds one's post(s) deleted for differing to OP's opinion. It suppresses healthy cross-fertilization of ideas when that happens. My observation is that despite the spam in the gambling board, moderators are hesitant in deleting posts there unlike their swift deletion when it comes to other boards. Do we take it to mean that moderators don't patrol that board often like they do others?
You've got two of the most active staff users on that section, so while they might not
patrol it, they're definitely around acting upon things. I don't know so much about Cyrus, as I'm not overly familiar with their duties, but I know they're very active at the very least.
I've reported a few posts over the gambling section earlier. Varying of different types, some which I'd expect to get handled, and then others which
might be somewhat borderline, which I'm somewhat expected to remain unhandled. Though, I do think they're pretty much saying nothing. I'll see how they get handled.
My suggestion for controlling spam on that board will be for moderators to lock any thread exceeding 50 pages, no matter how interesting anyone thinks the discussions going on there is. Secondly, campaigns should reduce their weekly post count requirement on that board to just five posts instead of 10. That way, participants won't hastily populate those threads with unconstructive posts and make them redundant.
Yeah, we tend to avoid locking threads. In my head, locking is usually useful in certain circumstances, which to be honest I haven't really come across in the years I've been here. If a thread is that bad, it would probably be just as good to remove it completely. However, in almost all cases I'd say its better to remove the problems within the thread, than the thread itself, and that goes for locking too. Others might have varying different levels, but we don't see threads getting locked much so I expect they have a similar interpretation on that.
Signature campaign managers can specify whatever they want in their rules, as long as it doesn't break forum guidelines. To be honest, even if they had a minimum of 20 posts a week, certain users could easily do that, without spamming. Some already do. It's the outliers which are willing to pretty much pump out anything, while still remaining somewhat borderline in terms of spam.
