in my honest opinion, we don't need one.. people would still look at it anyway if they wanted and also, if they are mature enough to make decent non-childish posts, they should be able to see this content.. just put spoilers on things.
also, having a massive variety of boards can be good but also bad because you may end up with 'ghost boards'; boards on the bottom of the page that hardly get seen so they don't get posted in but the OP is hoping people would respond to it because they were considerate enough to post it in the correct section
