No clue really.. I can't call it is why the frustration. I've been told every case is unique too. My rankings come and go they just didn't seem stable. If it is a penalty filter I requested a re-inclusion about 4 months into the change. I didn't see a change after either. To me it's the "google trust filter" that my site was lacking because I'm in the results and ranked on some terms but total traffic is 1/2 to 2/3rds down.
