Hi Dennis,
I've checked with our Policy experts and it looks like ad serving was disabled for violating our program policies. As stated in our program policies, AdSense publishers are not permitted to place Google ads on sites with content related to programs offering incentives to click links or ads, read emails, or surf other websites. This would include, for instance, auto-surf sites, pay-to-read email networks, and sites comparing various pay-to-click programs.
I really don't know what next move to do. Changing domain might be successful coz I've tested the code in other domain, and it works.
Well that sucks man! But atleast you still have your account and thats probably the most important. As in faucet related stuff I don't know if its good to start with another domain because there already tracking you so maybe next time you could get banned.
