Google is angry

Hello ..........., It has come to our attention that invalid clicks have been generated on the Google ads on your site(s). In the future, we may adjust your payment for any days during which invalid clicks occurred in order to properly credit advertisers for any invalid activity. As a reminder, any method of generating invalid clicks is strictly prohibited. Invalid clicks include but are not limited to any clicks that are generated through the use of robots, automated clicking tools, manual clicks by a publisher on the publisher's own web pages, or a publisher encouraging others to click on his ads. If you are clicking on the ads on your web pages for testing purposes, please note that clicking on your own ads or encouraging others to do so for any reason is prohibited, due to the potential for inflation of advertiser costs. Please be assured that there is no need to test the ads on your site, as our specialists review all of our ads to ensure that they meet Google's advertising standards.
