I totally agree with you. This might seems a bit rude but that's the hard truth. Any one who are doing extremely well with affiliate products will not and should not give out the product they promote. But what you can do is teach others how to test a product and see if it does well.
Well, some others said (at Google Adwords thread http://forums.digitalpoint.com/showthread.php?t=684602 ) these movie download sites are illegal to promote. I tried them, I promote exactly the same site, but two days ago, Google raised my bids from 0.20 to $10 on every keyword I put. What is the maximum bid per keyword do you have on these? $15? LOL.
gem.stocks - i guess u are very inexperienced with adwords. If u want to lower that bid, make a targeted landing page, than adwords will let u use the 0.20$ clicks.
