Smart Telecommunications plus an Adult Site?

Are you a user of Smart Telecommunication or simply Smart? Well, I am. If you are a fan of their Facebook page, you might see their upcoming promo because they announced that the said promo is a Huge Free or something like that. But the interesting and mind boggling part here is their policy for you to qualify.
You have to be 18 year old and above to grab their promo. What for right? Does Smart will put up a promo that has something to do with an adult content? Let us better wait for it because this is really exciting. =)
