I run affiliate programs for my businesses, none of which have a box for coupon codes when you sign up. Despite that, nearly every day new coupon sites sign up for the affiliate program. They usually have a webpage full of "coupon codes" offering discounts that don't exist made up, ready to add the referral link to. I remove all these sites from the program, some leave the pages up anyway. Even coupons.com has a page for my business with several "Click to Save" buttons that do nothing. They're publicly traded as well.
