The webmaster who got his account banned had the troubles to convince Google that the website that used his Adsense id was not one of his own which meant that his Adsense earnings would fall down to zero for that time.

Webmasters asked Google to implement this feature for a long time and finally Google decided to add it. The Adsense Setup tab of the Adsense account has a new tab called Allowed Sites. You have the option to add all of the sites that are your own and have the Google Adsense code implemented.

Ads will still show if they are implemented on a site that is not in the list but will not generate revenue. The problem that I see here is that it is not possible to get a list of sites that you probably missed when adding them.

I’m also not sure about cached pages and proxies which could turn out to be problematic if many of your visitors use proxies to connect to your sites.

Will you be using the new feature ?
