Moderators and censorship? Yeah, I have heard that one before...as a mod for a photo site, I get accused of the same thing. I have to give the mods here some kudos, I know what it's like. There is nothing worse then members who spam, flame, post content that is against the ToU and RoE (Rules of Etiquette) and then, when they get in trouble, they ask "What did I do that was so bad?" Over where I moderate, we just straight up ban for repeated offenses. There is a warning, and then if it's done again, they get the boot. We have a team of 8 admins on a site with nearly 40,000 members and 1,000,000 images, so managing that has it's moments. As a mod, I don't have time for adults that act like children, and post things to cause trouble. I have to applaud the mods/site owners here for restricting/forbidding posts on politics, or religion, the site I am on doesn't do that (the site's owner insists on having an "open" forum) Every day, we are moving, and or closing threads on religion or politics, because after about 3rd or 4th post, they turn into flame wars, and name calling festivals. It takes away from what the site is about, and opens the door to massive trolling.
So, you want to accuse mods of censorship? Not censorship, it's called "enforcing the rules".
