ClickFrauds offers an AdWords API with an algorithm that monitors web traffic and preempts threats in real time. Instead of sending an email notification about a threat, the system automatically bars the responsible IP address from the AdWords account. With constant uptime, the system performs cross-account analysis, identifying problematic IP addresses that might threaten a customers account. Once a malicious IP address has been identified within multiple accounts, the API blacklists it. Blacklisting entails joining an aggregated list of IPs drawn from all ClickFrauds accounts, forming a database of fraudulent digital entities.
