"SiteMeter only accounts for the last 100 visitors individually. On a site like Daily Kos, the 100th most recent visitor could have been 15 seconds ago. If you are the 101st most recent visitor and you click on a new page, you are counted as a new unique visitor in SiteMeter’s all important count. On a normal site, this wouldn’t matter, since it’s highly unlikely you’ll stick around long enough to have 100 others show up after you. On a site with hundreds of thousands of page views a day, it’s extremely likely you will."
so clicks can be manipulated.
How to manipulate them beyond the absurd to show the fraud?
