Webmaster Radio's Jim Hedger is causing quite a stir with his exposé on botnets, click fraud, and terrorists profiting from Google's AdWords program.
Hedger admitted in his post on Threadwatch that the terrorist part was sensational. The meat of the story is the prevalence of botnets. Hedger described some of his research into botnets in an article at SiteProNews.
I'm waiting to hear back from Google for their side of the story, and I expect to have more to share on this tomorrow.
UPDATE: Webmaster Radio has posted the audio file from Hedger's show, which is billed as the first in a series of shows on the topic. And I've posted a story with a response from Google over at ClickZ.
