Like I told you, NO.
They probably just look at how many times an IP clicked your ad and how often. Basically dont click it 5 times or your screwed. Also never click it yourself NEVER (I clicked it cause i actually found the ad interesting but other then that lol) I wont make the mistake more then once!
