I ask this because I used to be on another opinion site... And I was often flagged and reported for foul language and dark/inappropriate humor. The majority of those people complaining were conservatives who claimed they were "anti PC". Though they want to monitor my language... Seems like the term has a broader meaning than I though.
That's why the mods have a special group to log things that get removed, so we're removing things equally. We all read what's getting removed and act in unison or speak up if we think it shouldn't be removed.
And, most people do censor themselves when they realize we have language rules. That's one of the reasons we talk to members and don't use an automated system or yank content without saying why. Most people are content to follow the policies, as long as they know they're there. If you look at the blogs right now, you'll see a couple of people who didn't and chose to leave. C'est la vie.
Personally, I have the mouth of a sailor. I keep it in check on the site and around my kids a solid 97.3% of the time. I only moderate language because members asked for it. *shrugs* If I need to blow off steam, I go into free-for-all and curse at the walls.
