It's pretty simple actually, if you believe that it is "sick" or "wrong" to sell this type of content, then don't support it by promoting it... It is in no way illegal and in no way harming anyone.
Fantasy sells, and theres sick fucks out there, maybe they are fantasizing this girl is 17 years old... Maybe your spouse is fantasizing your a Shemale ?
So if it goes against your morals, dont promote it, dont bump the thread thus promoting it..
If you make money, sell it, earn while its fresh
