Google SEO Spam

Will someone please explain how things like this can end up in Google’s search results:

"hardwood floors md"

Low quality classified ad sites with single advertisers running thousands of ads in thousands of cities and getting ranked for them!!  It certainly seems to be working for this flooring company.  What do you “white hat” SEO’s out there think about this?   The search I did to find these was “hardwood floors md”.  If you click on the listings in question, you get pages like this:

Do you find value in this page?

Does anyone??  How do pages like this exist?  Do the big brains at Google have a plan to stop it?  It seems to be running rampant these days.

Anyone out there familiar with Creative Loafing?  Is it a viable concept?  Please explain!
