i think they all the clicks from same ip and google tracking system track it so it payed you for one click
I would rather say this sound like you are the one clicking on your ads. Be careful! Do not send people to click on your ads. (Spanish) Te lo aseguro que te eliminan la cuenta.
no it would show as 3 clicks in the reports so I guess it is only the first one that counted, I actually get this on one of my high traffic sites, and if they click on say four ads with so many seconds (Time period unknown and I have been doing my best to monitor it) then you either get one click or zero, I'd live with it. I monitor this by using statcounter, then when I see it happen and think click bomb, then I use "Jing" - not affiliate link just google it is free, but you can use it to take an onscreen image, save it and then email it to Google, just with a gentle note saying you think it might be malicious, Do not send them an irate note demanding the money for your clicks whatever you do, all you are doing is reporting a problem, all they are doing is protecting their investors, and as I also use adwords as well as adsense I am glad they do as should you be
