So we discouraged that, but we didn't ban people from swearing, or talking about adult things, or posting content that wasn't actual nudity. That would have been ridiculous... I've just Google searched adsense and "provocative imagery" and found examples of them blocking sites because of old posts about lingerie, "crude words", and somebody making a post about their sex life. Wow.

I figure this site doesn't qualify for AdSense at all then... Devil May Cry is fairly violent.
