If you use allowed sites only in your Adsense. Make sure to put your site in the allowed sites I had clicks today for $0 becuase I forgot!! xD
LOL, I once had like 5,000 impressions and around 15 clicks daily for a week or so on a domain I purchased that gave me 0$ I got frustrated (read pissed) and contacted Google saying that the site must have been banned since I am not getting anything from the clicks and impressions. The funny part was that Google folks did NOT tell me what the problem was.. I figured it out by myself. Cheers.
