I am doing adult promotion and i can tell you that it is hard to promote porn, that you have had some lucky sales is nice for you but i can say (and i have promoted porn for more then 4 years now) that it is getting harder and harder to get quality traffic with TGP's and tubes sites flooding the net with free porn, and not to mention the shaving and cheating sponsors, big traffic leaks on the tours like email collection boxes (where you not get credited for )or pieces of posts from review sites, no if i where a newbie Internet marketer i would stay away from porn until i have had some experience.
