I used to do that too until I found out google only counts one click (tracks your IP) unless of course you have a static IP or an IP cloaker 
Liveclear,
I would stop that right away if I were you.
1 it is unethical
2 it is called “click through fraud”. Basically stealing and it is a felony. Google has sophisticated programs that can track your IP address and they will catch up to you. Businesses are paying big bucks and Google doesnt want those big bucks to go away because of bad ROI. You are really screwing with google more than FISH.
