The issue is age, not fanservice.
People should feel free to post whatever bikini figure pics they want in here, provided they're clearly of age.
I think people have the wrong idea of what child porn is? By what you just said, having a picture of my daughter playing at the beach in her swimsuit is child porn. We all know it isn't I would like to think that everyone here knows what is actually pornographic and what is not.
EDIT: I don't have a daughter, I am just making a point.
