I'm of the opinion that there is more to Penguin than just analysis of backlinks. However, it is part of the problem, which is why I've been removing links for over one month.
However, as we know, not all webmasters respond to emails. So if links are truly out of your control, is it an option to block referral traffic from that specific IP address and therefore 'kill' the link? Or would it just result in a world of pain?
