There's actually existing vision recognition software that can identify a blow job, and blur out the relevant part of the pictures. Such software is marketable, although I think it was an academic paper. I'm not going to look for a link at work, but I do remember it was robust with respect to rotation of the picture, which made for some amusing collages.
