...to what? To Penguin merely devaluing links? So to stop Penguin devaluing links, we use the disavow to devalue the links before Penguin devalues them? What's the point of that?
I have no idea. Perhaps it's a kind of trust building exercise / "truth commission", where Google is "prepared" to restore a site back into a higher level of trust when it removes links and/or disavows them, if it first admits to it's bad practices.
This isn't new. In 2007 I observed inadvertent participation in a link network , which cause a site to be filtered out of the SERP's. Removing the links caused the site to return to the SERP's within weeks. Google knew these links were bad, and preferred the webmaster to fix it. The same principle may exist under Penguin with some more complex considerations associated with it.
