I cant believe that ArchLinux http://www.archlinux.org/ hasnt been banned (or atleast warned) by google for placement of the adsense ads so close to user-controls on the website. Pretty sad. The ads could have been tastefully implemented without detracting from the webpage but they've failed to do that.
They probably just didn't notice the new rule of AdSense. I'm quite sure they won't be banned as the policy is still new and not all publishers know about it.
