There really does need to be a difference between nsfw (nudity / lewdness) and nsfl (gore or vileness), because right now if I block the one I can't see the other, when I really want to block the one and not the other.

There is an option, op, for blocking all nsfw. In your settings, right beneath the languages, there's 'theme,' 'type,' and 'sort type,' and then right beneath those is the little button that can be checked/unchecked for 'show nsfw content.'
