These sites have just as much reason to be in Google as any other. If a site has a "search?keywords=" in the url it could also mean they are pulling from their own database of content - so you want to penalize them, also?
BGumble, these sites have value. Are you going to include DMOZ in your spam report? How about Yahoo?
