To summarise - there seem to be two ways google may find where the clicks are coming from from the perspective of potential ban 1. IP Address 2. Cookies The Cookies are easy to deal with. Just do not allow your computer to be used by someone else. For IP address, find the ip address of the campus computer (s). To be safe, disallow the google ads on those couple of campus ip address. If you are a php coder use following code $ip = $REMOTE_ADDR; if $ip != a.b.c.d // assume a.b.c.d is your campus ip address { // javascript google ad code here } If you are using some blog websites you may have to use javascript. My best bet is you will not be penalised unless the clicks on Ads reach at least 100s. So you should be safe.
