Actually I have about $ 0.3 daily as a click but I don't know the source of it. I have checked my channels but none of them were involved in that ? is there anyway I can find out about that ?
well.. maybe somebody has stolen your code and inducing clicks. beware of this activity. if you are unknown about the source, better inform google immediately. this can happen if someone is trying to clickthreat your account. also, you can use the 'site blocking' feature to limit adsense activity from websites which are approved by you. though '0.03$' is too low. but, better inform google and revise your traffic logs to see if there is anything suspicious..
