tanveer1979 writes "A seller of online marketing tools has sued Google over click fraud, accusing it of failing to protect clients from spurious clicks over web ads. The suit claims damages of $5 million and is seeking class action status. Sites get money per click from the advertisers. Rival companies of the advertiser may employ people to repeatedly click on the advertisers link on Google costing them large amount of money. Google denied the allegations. From the article: 'We believe the suit is without merit and we will defend ourselves against it vigorously.'" Interesting turnaround.
