When we asked Google's Gary Illyes about Penguin, he said SEOs should focus on where their links come from for the most part, but they have less to worry about now that Penguin devalues those links, as opposed to demotes the site.
Google's manual action team has access to look at a page's link labels and may use that to dig deeper into the site's activities.
The latest announced release, Penguin 4.0, will also be the last, given its new real-time nature.
