AdSense in China Take Initiatives to Protect Publishers

According to the Official Google China Blog, AdSense China has announced a new feature in hopes to protect publishers' account from being sabotaged which they call it Allowed Sites. Publishers can enter a list of allowed domains (in which they own) and only impressions, clicks and earnings generated from that list of sites would be reported in the publishers' AdSense account.

The main aim of this feature is to prevent publisher IDs from being placed in spammy sites that do not below to those publishers. Currently, you can enter up to 100 sites in to the allowed list and would take up to 4 hours before the list is activated.

What is interesting is that ads would still show up in sites out of the list though any clicks wouldn't generate earnings for the publisher and there is no mention whether advertisers are charged for these clicks.

It seems that this feature is has not yet gone international. AdSense publisher, would you welcome this new feature?
