Ad fraud is strictly prohibited. Ad interactions generated for the purpose of tricking an ad network into believing traffic is from authentic user interest is ad fraud, which is a form of invalid traffic. Ad fraud may be the byproduct of developers implementing ads in disallowed ways, such as showing hidden ads, automatically clicking ads, altering or modifying information and otherwise leveraging non-human actions (spiders, bots, etc.) or human activity designed to produce invalid ad traffic. Invalid traffic and ad fraud is harmful to advertisers, developers, and users, and leads to long-term loss of trust in the mobile Ads ecosystem.
