Uh... I'm sure there's other Final Fantasy sites which'll allow you to post sexually explict cosplay pictures of yourself. I know you want to here, but rules are rules.

I think the rules are considerate to younger audiences, and older ones who do not wish to see swinging genitalia or what have you while they look through the forums. Also, that type of display would attract unwanted attention from people we don't really want influencing this board.

If the games had higher age ratings, then it would go up also. I think Final Fantasy games are like rated 15 or something? Probably lower. If a twelve year old types "Raising chocobo's FFVII" in google, and comes up with a FF site full of porn and trolls, will they want to stay around long? Just a thought.

Keeping it family friendly allows a larger group of people to come here. As mentioned above, you can make NSFW topics if they're clearly marked, and that the content obeys a few rules. It's not really a big deal.
