Google Now Penalizing Subdomains Leasing, Not Just Subfolder Leasing

As you know, Google warned publishers about leasing out portion of their sites so that third-parties can piggy-back off the site's authority and trust and rank their content better. Google then began penalizing some of those sections on the web sites that are leased out. Now, Google is not just penalizing the subfolders doing this but now also the subdomains doing this.
