I do have another plan, actually idea is adapted, maybe you should offer a bit low, like
-Instead of upto $40 offer $30
-Make hybrid plan a bit low, like 50% of downloads + 25% of sales
-And individual affiliates also, like Just PPD or PPS or Hybrid
If you work in this way you don't need to block traffic, cause you'll see the number of uploaders are decreasing, so less uploads decent traffic. Just because of your crazy Money offer brings you this huge uncontrollable traffic. Hope you got me
