The more sketchy the advertisers become to one up each other (like adding forced upsells that are virtually impossible to notice and not even a checkbox but a image button to remove it) to faster that niche will be killed, regulatory agencies such as the AG and FTC will get involved, publishers and ad networks will stop allowing it, etc etc.
I mean rebills are what they are but when you force an upsell that is often completely non-related and that the user would have no interest in nor know they even signed up for it then it's only going to fuck things up for everyone that much faster as well as bring all the legal troubles to the advertisers door. I understand it's a competative industry and everyone from affiliates to networks to advertisers are at each others throats to beat each other out any way they can but damn some of us are cutting off our own nose despite our face. We can all make insane money, keep risk down, and do it for a long long time to come if some of us used our brain and thought about the future a bit before pushing the envelope as far as possible for the extra quick buck today.
What's next a hidden triple forced upsell so the user gets a $300 CC charge the moment they hit submit on their teeth whitening free trial?
