I find this very difficult to understand. My site is completely gone for ALL keywords even the long trail stuff. The site was built with the updates in mind. It's an EMD with got all original content with about 20 or so 1000+ word articles all written by me. I update it weekly with more quality content. It's young site only a couple months old, but it's PR3 with only quality links point at it. The first tier web 2.0 has all original content with several posts on each web 2.0, all other first tier links are quality links from within my niche. I did spam the web 2.0's but it was done through mega huge pyramids 3-4 tier using SENuke. I don't get it? I can however find it by doing an exact domain search so I guess it's not completely deindexed. As far as on page SEO pages it isn't overly optimized, not spammy at all. I used about 2.5-3% keyword density and did some good interlinking.
