I was at school one day and I was explaining to a kid how my site works. I was logged into my adsense account. He said "so if I click this, you get money?" I'm like "DON'T!!!!" He says "Oh, ok" and clicks it anyways. I log in most of the time at school (highspeed internet). Should I contact Google about this? Also, I have earned nothing since that click.
one click shouldn't be a problem but logging in to your account from school computer is not a good idea since anyone using that computer and clicking your ad , Google will assume that you are clicking.
adsense-support(at)google.com You have to stop login to adsense at school and anywhere else except you home
Rule no.1: Never share your site with your school/Office friends. Even though they are your great friends they might unintentionally land you in trouble. When it comes to money, Play Safe! By not telling them, you are neither loosing them as your friend nor loosing your account. Anyways 1 click is petty and google wont even bother to check that. Relax and remember this next time.
