Quobuzz are the latest content thieves we've come across that have blind theft - i.e. the script is set up to steal from everyone, not just certain sites.
2,220,000 sites scraped so far with huge adsense ads above the scraped content.
It's a poor quality theft, that just uses "hidden" CSS tags to hide the stolen content when you view the page. Obviously, the Google cached version of any page and a quick look at the source code of the page will show the scraped content.
