Who owns 67337?

I like to note on the US Short Codes Whois directory who the owner of a shortcode is. But the owner doesn't always make it so easy. 67337 sells all manner of premium content, from horoscope alerts to games to riske wallpapers. The wallpaper is not porn because the carriers don't allow that, but the bikinis are still quite small. In the T&Cs, it refers to MyCoolmobile.com, but it never tells you who the actual company is. Why is that? Who has somthing to hide? The website domain registry is also private.
