This is also one of the reasons the launch of Penguin 4.0 on September 23, 2016, was a welcome change among site owners everywhere. While it took quite some time for Google to finally release the update, many would agree that the wait was worth it. In a nutshell, Google released the Penguin update to detect spam automatically. More impressively, the Penguin 4.0 update runs in real time when it comes to recognizing your site cleanup efforts, thereby eliminating the effect of your site being suppressed up until the next time they run the algorithm. That is, Penguin 4.0 stops your site from getting demoted when a spam is detected. Instead, it will just devalue that link and allow you to move on without benefiting (or suffering) from its presence.
