How do you know these are fake submissions? Google's announcement provides more incentive to sumbit both types of complaints, fake and true.
That's the point of it. It will not be easy for the google people to easily tell which they are dealing with so it will slow the whole process down tremendously. Slowing it down will help breath a bit more life into the made-for-adsense (MFA) sites that rely on other people's content so they can continue to milk the revenue for as long as possible.
This is google's own creation so I'm glad to see they are now facing a nearly insurmountable task of reversing it.
