I realized that I've got 13 consecutive clicks propably clicked by same person yesterday. Google must have already detected it because they gave 0$ for those fraud clicks. Regarding that they have already detected the fraud clicks and gave no money, should I contact them or the situation is already under control??
it wont be fraud click if its not coming daily base from same IP , keep watching visitors ... Google wont ban you if you get just 13 clicks from same person but if its coming again and again then they have to ban your account to protect advertisers cash
thanks for the replies. I read somewhere that if adsense checks and detects automatically that a click is fraud and it's not from your ip there shouldn't be a problem. If it would we could just make people banned easily.
