This is the best site. I have checked other sites that are in the top in Reviews Site. They indeed offer high CPM. For some country more than this site. But they restrict 1 user per IP and doesn't count more than that. But Clicksfly not only allows 1,2,3....But 5 users from the same IP. That's a fact. Just use the network and check it for your self. It's so clear that you will see the difference in your 1st day.
