We take the quality of our ad traffic very seriously, and you can be assured that our proprietary technology aims to remove clicks and impressions from unethical users and automated sources before they ever reach your account. In addition to our automated click protection techniques, we have a team that uses specialized tools and techniques to examine individual instances of invalid clicks. When our system detects potentially invalid clicks, a member of this team examines the affected account to glean important data about the source of the potentially invalid clicks. One of the goals of our team is to make invalid activity very difficult and unrewarding for unethical users, thereby decreasing their chance of success.
I won't let them display off Google properties at all any more.
