Tapjoy has invested significant resources and money to develop our Fraud Detection and Management technology. We use a multi-method approach, including various data-mining, algorithms, and heuristics, to identify fraudulent behavior and users. This ensures high lead quality for our advertisers, and in turn translates to higher advertiser fees and revenues that we pass on to you. It also reduces the amount of chargeback handling with direct payment options such as PayPal and mobile payment providers.
