Quote - A character could have size 99 ZZZZ sized boobs, but if the face looks under 18 years of age (IE: has a lot of child features), that character is considered a child and the image is removed. Those decisions aren't made arbitrarily.

This is a bit like saying the Red Queen thinks before she acts. Yeah. No doubt. One of the safest rules of thumb, I've found, is that the same people who get sweaty over porn want porn illegal because that's what gets them sweaty -- not the porn. We've taken to calling it Larry Craig Syndrome.

You are right in your initial analysis, and that fact all by itself demonstrates the idiocy of the rules. A 40-year-old man can have the facial characteristics of a 12-year-old girl, but nowhere on the planet does there exist a 12-year-old girl with 99ZZ boy toys. If the body is mature, the face is adult, however puffy and pouty and pseudo-adolescent. Manipulative adult women are working overtime to look like little girls who want a taste, and in this absurd milieu we are trying to protect ourselves from meshes that might make some men think of little girls. The face thing is ridiculous, like deciding the mesh is a child if it has long toes.
