I can’t imagine identifying naked people or pornography to be computationally hard (the difference include hippies on holidays or medical images, typically dermatology, and you want that even less) at least not for a search engine with image previews.

Not that its computationally hard to say is this a naked person (#notahotdog from silicon valley). It's more along the lines of show me all naked pictures of ME on the internet, is probably more computationally hard.

showing me all the naked pictures of ME on the internet is just a null function
