Quote:Click fraud is a type of fraud that occurs on the Internet in pay-per-click (PPC) online advertising. In this type of advertising, the owners of websites that post the ads are paid an amount of money determined by how many visitors to the sites click on the ads. Fraud occurs when a person, automated script or computer program imitates a legitimate user of a web browser, clicking on such an ad without having actual interest in the target of the ad's link. Click fraud is the subject of some controversy and increasing litigation due to the advertising networks being a key beneficiary of the fraud.https://en.wikipedia.org/wiki/Click_fraud
Any talk of website investigations by the Feds is most likely related to click fraud. The advertisers have become wise to the scam.
