if people are using these domain names as a form of advertising, wouldn't it be in Googles best interest to stop this technique.

Not if they are running Adsense on these sites. I tend to think about the long-term. How long do you think G will keep these sites on the first page? Is it worth your time, effort, and money to do the same thing? I can't really say, since I don't know your niche or the content on these sites. Personally, I wouldn't bother setting up a link farm that could in the long run hurt your main site.

Current trends seem to show big brands poping to the top of the serps.
