The way I beat the filter to was make my commercial site look like a directory. The filter looks at the site and filters on the commercial element. It is easy to determine which sites are commercial and which are directories. Before Scr**gle ceased to work it demonstrated the filter at work. Brandy has removed the filter for certain city terms, but not most. The best way to find out how to beat the filter is to look at the sites listed.
I find the way by noticing a commercial site which managed to reappear. It simply developed a directory structure. This means link out to relevant sites and receive links from relevant sites and make sure these are not same sites. It is best achieved by having multiple hosts and domains. I did it using 3 domains which were on two different servers and all had the same topic (but very different content). Two of the sites are filtered out the other sits in the #1 spot for a competitive keyword. I know the filter is not based on over-optimizing because the 3 sites share an equal level of optimization. It is only the linking structure that seems to trigger the filter. Look as I said on how your site links out to other sites in the same theme this is the answer.
