as i see it even if it's ok with Dannicash and Spacash you forgetting the most valuable point you sending a message to surfers "why pay for something if you can get it for free ? " and really do you expect people to click and buy from ads if they download for free ?
there is possobility they will but defenetly not on your site ! why should they if its a free site where you can download so many free porn movies ? bad busieness move dude !
