QuoteKrebsOnSecurity looks at a popular service that helps crooked online marketers exhaust the Google AdWords budgets of their competitors.The service allows companies to attack competitors by raising their costs or exhausting their ad budgets early in the day. Advertised on YouTube and run by a guy boldly named "GoodGoogle," the service employs a combination of custom software and hands-on customer service, and promises clients the ability to block the appearance of competitors' ads.
