I think moderation isn't bad if it's not too nazimode. I mean if people post a whole bunch of scat and guro on /a/ over a long period of time, that means that the site admin(s) should make a board for scat and guro hentai. If such a board where that content is appropriate already exists, then I see no reason to allow users to unnecessarily post it on other boards, just like I feel like /a/ shouldn't come and post unrelated content. It's not fair.
