About the referral system: Why don't you implement a system like this: to be credited by referrals you need to click X ads everyday, If you don't click, you don't earn the referral income from the next day, the same NeoBux uses and seems that work...
With a good referral renting system your site can boom like NeoBux and become the King of Bitcoin's PTCs.
