The Google Play Store is easily one of the largest mobile app repositories on the market, with over a billion users that use the service daily. With that kind of traffic, there are bound to be some scammers in the mix. Google has never shied away from deleting apps, and even banning developers who engaged in problematic behavior. Today, the company has deleted over 600 apps from various developers for displaying disruptive ads

In 2018 Chinese app developer Cheetah Mobile was penalized for committing ad fraud through its network of apps. The apps were subsequently booted off the Play Store and the company almost went with it. Today, 45 of Cheetah Mobile's apps have been removed off the Play Store for ad-related transgressions.
