If Penguin were a 100% mirror of manual unnatural link penalties, then I think we'd know that by now. It's more complex than that - I've seen sites hit by Penguin that didn't match that kind of "unnatural links" profile
This has been explained to Fathom over and over and over. We have also explained that when Google says we'll never backward engineer Penguin, chances are it's a bit more complex than "spammy backlinks r bad." Additionally, we have pointed out that if all Penguin does is something the also always did (look for spammy backlinks), then Google just wasted inordinate resources and is deluded to derive satisfaction from what Penguin is doing.
It never gets through. Trust me. But the rest of us understand that Penguin is more sophisticated than that, so please don't get derailed by this.
