Yes I read it and I think it is a bunch of BS written by someone who obviously doesn't understand the Domain business, PPC Advertising, or the concept of Virtual Real Estate.
What I don't get is why they are so worried about click fraud anyway. It's just a cost of doing business if you ask me. How come a large corporation has no problem spending millions of dollars for a thirty second ad on a popular show or the Super Bowl, when that ad is far from targetted. Most people get up and go to the bathroom and very few are interested in buying the product.
At least with something like Google Adsense or Search, it is very useful in connecting business owners/advertisers with consumers who are actually interested in their product/service. I'm sick of being bombarded with ads I could care less about on TV. I do most all of my buying on the internet and use search and ppc ads frequently. So what if a few of the clicks are bogus.
