Well dont get too confident about google not knowing with google earth and google maps they may just have a camera over you friends shoulder with you standing right next to him as he clicks on the ads! Funning aside never let your friends know that the links on your site when clicked make you money.
Incorrect... My site was click bombed recently by someone. I received 100 or so clicks and contacted google immediately. Their reply email basically said not to worry about it. EMAIL BELOW: Hi, Thanks for letting us know about this situation. Rest assured that we've noted your input, and we'll continue to monitor the situation closely. I understand that you're concerned about keeping your account in good standing, and that you'd like more information about the recent activity on your account. However, because we have a need to protect our proprietary detection systems, we're unable to provide you with any details about your account activity. I also realize that you might have questions about what Google is doing to prevent invalid click activity. You should know that our specialists carefully monitor clicks and impressions on Google ads in order to protect your interests as well as those of our advertisers. To do this, we use both automated systems and human reviews, analyzing all ad clicks for any invalid click activity that may artificially drive up an advertiser's costs or a publisher's earnings. Please note that according to our Terms and Conditions, Google will use its sole discretion when determining instances of invalid clicks. Lastly, I wanted to let you know that in the future, we may adjust your payment for any days during which invalid clicks occurred. This helps us protect the integrity of the AdSense program and properly credit advertisers for any invalid activity
Your fine....3 clicks is fairly normal... I have had this happen to me as well....it is not your friends fault they just don't fully understand the rules...
Rule Number 11 - You should never show ur site (with adsense ads) to ur friends, Family, Relatives In case u showed them ur site then you should never tell them about Google Adsense - that you get money for clicks etc.. etc.. anyways from next time take care, no worries this time
Well I got banned because someone with very bad intentions clicked 3.846 times at my ad in one night...google closed the door immediatly ..no discusion was possible. Thats the scary thing about adsense, if someone doesn't like your website he could screw it up for you bigtime.
