What if we took different size sliding windows, and moved them across a large dataset, and fed the resulting chunks to a pornographic image detector to look for what is likely a completely random set of data that can be re-interpreted as pornographic (or more importantly, illegal in some manner)? How much does creation matter compared to existence, compared to use? Does a formation of clouds or rocks that looks a certain way also fall under this category? With regard to illegal child pornography, I'm sure it has a lot to do with the wording of the law, but I think the intersection of how laws are defined and how they may conflict with the natural world (including randomness) is itself interesting.
