GI works but not real well. For my proxified pages I use (listed in performance order)
I get an average of around $2 a day from GI, Adtoll is good if you have a good Alexa rank as you can charge advertisers more and they will pay.
GI works for me as it makes it deposits via paypal around the 18th of the month. I think there payout minimum is $50 never missed a payment only thing I dont care for is there interface on the account panel.
