GOOGLE in European antitrust inquiry - Search rankings and advertising service to be probed... Is Google utilizing its strength to keep some advertising pricing over inflated? Not the first anti-trust review however the details are interesting... What are your thoughts?

I just analysed a Google AdWords campaign and it appears that in our case the majority of clicks come from fraudulent websites as well.
