ALERT ALERT! Penguin “Double-Take Update” in progress. Search results are extremely unstable with preference for low quality links, anchor text manipulation and link networks. If you've been doing blackhat, this may be your lucky day. For the rest of us, let’s hope this is only temporary. +Bartosz Góralewicz noticed Penguin roll-back and wrote about it here: http://goo.gl/vQ4THu. Now we have additional evidence to support his observations.
