Member profile information for a control set of one or more control members and for a fraudulent set of one or more fraudulent members are obtained. Each member in the control set is at least believed to be legitimate and each member in the fraudulent set is at least suspected of being fraudulent. A test associated with identifying fraudulent members is generated using the member profile information for the control set and for the fraudulent set; the test inputs one or more pieces of member profile information for a member being tested.
