The law is more of an extension of my morals. If something is illegal, I am obviously not going to promote it. Anything that I feel is reprehensible in any way I will not promote it or allow it on my sites. In the end, my sites are mine and it's up to me what goes on them (assuming it's legal). I run a network of TGP and MGPs and I come across galleries all the time that are legal but I find them objectionable for one reason or another. One example is this gallery
http://www.gene-juice.com/galleries/...dexTFF_TG.html which has the title "Such Big Cocks, Such Little Girls." That line makes my skin crawl so I always decline it. I'm on the verge of just getting rid of that submitter completely.
In answer to your question, if 16 year olds could legally do porn, I would not promote them under any circumstances. I would cut ties with anyone who did promote them. 16 is too young. I agree that 18 is probably too young too but that's the way the ball bounces. There are a lot of things that I won't touch in this business that are legal. Cock gagging/forced blowjobs, simulated rape, pissing and really disgusting cumshots to name a few. I also hate sites that clearly cater to pedophiles (like little april). If some people want to promote it, great. I can't stop them but I assure you I won't be promoting that site or any site like it.
