Sorry you didn't see our announcement back in December. The Offer and Survey market has changed a lot in the last several years. To keep moving forward, we increased referral commissions on surveys last year so our members could make more. Survey commissions were not paid on the second level, so the loss should be pretty negligible. You can see more details here:
Eventhough the second level is gone I still think that Cashcrate has the best referral program. We can earn more money this way because you are in control of getting your first level referrals but don't have control of getting your second. Thanks alot CashCrate!
