@somid3 I would like to invite you to our analytics community: http://www.innerjoins.org

and to @vivekd's request for data on this topic: https://my.caura.co/investigating-fraudulent-clicks-in-googl...

- plenty of data here. Happy to provide a SQL interface for it if you can prove that you've got the chops
