I've been running, maintaining and shooting content for my CCBill pay site
TrueAmateurModels.com for 13 years now and I have many, many affiliates that are sending in re-bills every month.
I have NEVER EVEN THOUGH ABOUT doing that before .....and of course, I never would do that to my affiliates. That's just really fucked up.
I would imagine that as soon as those emails are sent out, that program would most likely LOSE a lot of those re-bills as a result of the affiliate saying .... um okay, no problem. I'll just remove all of your links from my site. That way, neither one of us will make money.
I can see this type of shit really backfiring onto the program owner. Shitty move to make on your affiliates ...whether they are still promoting your content or not.
