I didn't at all advocate consulting UD, I'm not sure where you got that. I've researched all major rule 34-oriented things. While 34 can encapsulate real forms of pornography, considering the ease of which it is to draw a picture versus enact something, and how theoretical fictional ideas will always outnumber real possible ones, it's a fair argument to say that 34 is predominantly cartoon. Unless the term has it's own article, where's a better place to redirect it than here?
