Not to mention that the last time I worked on image board code there was a list of auto-ban rules the server checked on posting, which included the MD5s of child porn. Posters may be more sophisticated now, tweaking a pixel to make the hashes not match, but there is software that can match the background scenery now with the illegal part removed that can catch even that. We didn't have an auto-ban list for drawings of it, though. That was up to the normal human moderation.
