Nothing wrong with the affiliate code overwrite IMO, survival of the fittest. The blacklisting coupons thing is the bigger fraud here. I couldn't help but notice that it never found coupons. I still have Honey installed at the moment just for the price charts to catch when Amazon is trying to ream me with a fake sale. Will happily replace it if someone has a better alternative.
Interested in seeing what exactly the second half of this video is about.
My company has an affiliate program, one affiliate started swamping us with traffic. I called it out as some kind of botnet bullshit, but was shouted down because of how much revenue this guy was supposedly generating... well long story short is he found an exploit for our affiliate program and was getting credit for any otherwise uncredited sales.
