In China, a man visits a click-through farm consisting of more than 10000 cell phones charged with leaving false opinions and good ratings to mobile applications. What's the point? On the AppStore or Google Play, there are millions of apps and games. Difficult for a developer to get out of the lot. That's why some people use click Farms. The phones will download the application, leave false good ratings and fake good reviews. The application will go back up in the store's ranking and have more visibility. This is of course fraud and it is forbidden by the terms of use of the application stores, but it costs less than a publicity campaign.
