Not sure why comment here rather than on the blog posts about adsense and that industry. The adsense ads change frequently so I don't see it. Sure, that site looks like SEO Spam, I guess it just shows that google large automates that process.

The search engines do have to do something about SEO spamming of this sort, I agree. I'm getting frustrated that so many searches now turn up this machine generated content.

Google has an aversion to manual tweaking (outside of China) but they have been reported to have done it, even gotten sued over it. One of the problems with manual tweaking, blacklisting SEO sites etc. is you are going to make mistakes, and at best punish innocent pages and at worst get sued. It will be an interesting legal question what doctrine sites will sue under, but that doesn't stop the cost of lawsuits.
