Popups in these amounts are excessive and irritating. I myself am a faucet owner (see
http://bit-vortex.com) but I only use one set of popups. Users can also earn 18,000+ satoshi per hour **guaranteed** at my faucet. compared to an average of 1008.8 satoshi per hour at yours'.
I think you should be slightly less greedy.
It is hard to gauge the rates until i have more users.
Another rate increase is going to happen tonight.
I sympathize with you. I think with that many popups, though, you can afford to pay more.
