I don't know why strange things happen to me i usually get 10-15 clicks daily on ma adsense but today its surprisingly 125 clicks and itz only for 1.37$ is it ok ............i don't think so
I'd fire off an email to G, you could have been click bombed or somthing else, but it may well be worth informing them, incase you get 'that' email....
its a problem with reporting. happens to me alot, sometimes I get 100+ clicks, not much much money, or traffic. ( before i was banned ofcourse )
