Earlier this month DaveN bitched about Thomson spamming AdWords.
The content on these websites ranges from facial cosmetic clinics to poor credit home loans to the "once in a lifetime" opportunity to get rich by taking online surveys. Any way you look at it, the ads appearing for the term "Google" (the same company largely responsible for the changing face of advertising) are completely irrelevant.
I spotted another AdWords targeting gem today, seeing an Seo Book ad atop a domain park page about credit reports. Is Google matching WhoIs data with their ads, or how did they get CreditReportWeblog.com to be a relevant page for Seo Book?
