Google Says Leave Us Alone (but still dont click your ads)
Inside AdSense: Accidents happen
Due to an annoyingly high volume of people accidentally clicking on their own links, Google has asked that folks stop reporting it to them. Google feels sufficiently confident in their click fraud detection algorithms to catch occasional publisher-generated blips and not bill advertisers. It’s still worthwhile if in doubt to let Google know, as they often cut publishers off without payment, resource or explanation.
