Need Help With Bad Google Listings

[RTK]

If the pages in the search results that you are worried about truly are spam, fraud and illegal - report it to Google online, and send them a registered letter.

They do look at things that are serious. If you go that route, make sure you yourself are following Google guidelines down to the last point...

As you didn't provide any examples, it will be difficult to provide other suggestion. Having both urls - the search terms in question - and seeing how the pages appear in the SERPS for you - might help.
