I know you can't have anything adult on a site that has CJ affiliate links, but what if you have an adult site, do they ban you if you put a link from your adult site to your mainstream site which has the CJ affiliates?
No they would not ban you. They can look at the site from where their affiliate link is being clicked. If you have website1 (non-adult) which has CJ link and if u r driving traffic to website1 from website2 (adult) they would never know about website2. I dont do such things nor do I recommend anyone to drive traffic from adult site. But I just told u what i knew
