I've had posts silently deleted from Greg posts. Turned out it was Greg's post that got deleted but a quirk of the DPR forum software is that replies to deleted posts get taken as well. A deleted post is not necessarily a deliberately deleted post and you shouldn't jump to conclusions about that.
You might also be interested to know that the mods decided on an approach of excising sections of posts that they felt broke the rules rather than just wholesale deleting posts. I protested about this because they were doing it silently which, aside from the censorship aspect, meant they could risk effectively deciding the meaning of a post even to the point they might end up changing the original meaning and putting words in the mouth of the original poster. I suggested they left a comment to indicate when they had made an edit, which they agreed to. That is their policy now. They do listen.
Deleting a post, editing/censoring posts or any other mod strategy is a slippery slope/risky policy. Any form of moderation brings with it the risk of bad decision making. But anyone who has used DPR forums must surely understand that moderation in some form is essential, it's the wild west at times. I've privately disagreed with some stuff, but at no point have I ever felt in my discussions about MF forum mod policies that they have been doing anything but trying their best to be scrupulously fair. It's just in the nature of such things that not everyone will agree with their decisions.
The bigger problem DPR moderation faces in my opinion is that the sheer size of their forums (compared to most photo sites) makes it all but impossible to properly police moderator decisions and whatever appeal process that exists is unlikely to satisfy someone who has got on the wrong side of mods. Another problem is that there is no official method of explaining mod decisions to the community, the result being that banned posters just disappear, which is unsatisfactory to say the least. But don't blame the mods exclusively for this, they work within the system established by DPR management. The massive size means the need for better management of the forums, something which requires more resources than have been committed. But to be fair to them, moderation wouldn't be necessary if posters could reign themselves in a bit. A bit of self-discipline is all that is needed to keep things civil, but at the first excuse people just let go... Does anyone remember the original Rob Galbraith forum site? It billed itself as a forum for professionals with very high standards. The moderation was draconian. For instance, mentioning hopes about the specs of a yet unreleased upcoming product would bring the mods down on your head. A free-speecher's nightmare. But it was a very polite place to post and very professional. If that was what you wanted from a forum it was the place to be. DPR is severely un-moderated in comparison and it sometimes shows in flame wars that would would have made a UseNetter proud.
