Yeah, your faucet have small amount of ads, but you can't monetize faucet with only few a-ads banners. Try to apply to more ad networks. Now it's hard to be approved on best paying networks, because your site is fresh and with low Alexa rank.
And it would be good if you add second captcha option. Sometimes Recaptcha is very annoying - it's so hard to solve it. Maybe try to add SolveMedia or Bitcaptcha.
Thank you for your opinion.
We are now waiting for the BitCaptcha to verify our site and if everything goes well we will be using their captcha service!
