If you are saying that interlinking between owned sites appears to be your culprit
Not really, no way to know that at this point since it is commonly believed that penguin has not been re-run since October 2012(?).
I was talking more about google ranking pages other than the pages being targeted by junk links for the keywords we are targeting. It feels like it's a "loophole" in the algo. Almost like they know that you are creating junk links so they're not going to rank the page for the keyword but then something bigger kicks in and say this site must be about "keyword" so lets find a page to display.
