From the original article: "The good news, whether you were hit by Penguin the first time or this time, is that you can recover.
We’ve now seen that this can happen, and since we know that Google will continue to push data refreshes for Penguin, there should be plenty of chances to do so.
Just think about all the Panda refreshes we’ve seen since February 2011.
We recently reported on WPMU, a seemingly quality site with plenty of fans on social media channels, which got hit by the first Penguin update. The site has now made a full recovery."
