I asked this on a different forum of Chad, and basically the warning page is an industry thing it does for some sort of "hey I tried" if taken to court, but it has never been tested. Basically, it's your call. I would definately be putting some keyword text into the index page, and would even consider the warning be made up as a graphic image that the SE wouldn't read and carry that text into the SE results description, or use an I-frame approach.
