Spam Clinic for German Web Sites

All the talk about Google banning BMW.de, Ricoh.de and other big non-US brands has inspired me to launch a spam clinic especially for german sites. Every now and then I stumble across a German SERP and I do not like what I see. Spam rules Google.de and I don't get why Google has an 80% market share over there. I do speak German, so helping to clean up these cluttered SERPs should be a home match;)
