Washington Post: 35 percent of Google's pay-per-click revenue is FRAUD: "A firm called Radiator.com got sick and tired of what appeared to be totally bogus clicks on their ads, then they hired an outside auditing firm to help them figure out what was going on.  Because of course, Google completely ignored their requests- everyone knows that's their standard business operating procedure. The findings?  Around 35 percent of all clicks from their Google ads were complete fraud, and about 17 percent of the clicks from their Yahoo ads were complete fraud" —F'edGoogle

This is going to end badly.
