I will be launching my faucet soon and i want to be making as much money as possible, which ad networks pay the best? they dont have to offer paypal cashout
Instead of relying only on advertising revenue I suggest you to add some gambling games(dice for example) to your faucet if this is possible,people seem to like them a lot and it will help your site survive.
Also, would you guys be interested in buying ad space?
Yes,if the price is reasonable,you have quality traffic(no bots) and my ads are getting many impressions I would be interested in buying ad space.
