Abstract: Systems and methods are disclosed for determining fraudulent entities. The method includes retrieving characteristics data associated with known fraudulent entities. A first graph is generated based on the characteristics data associated with the known fraudulent entities, the first graph represents relationships among the fraudulent entities and related entities of the known fraudulent entities. Identification data associated with a target entity is received. Characteristics data associated with the target entity is retrieved using the identification data. A second graph is generated based on the characteristics data associated with the target entity, the second graph represents relationships among the target entity and related entities of the target entity. The first graph and the second graph are compared to generate an association score for the target entity. Investigative targets are determined based on the association score.

Abstract: A grip for use with a sports implement extending about a longitudinal axis. The grip includes a flexible strip defining a length defining a major dimension and width defining a minor dimension. The strip has a butt end region, a primary region and a throat end region. The throat end region defines at least one guideline. The guideline extends along an outer surface of the strip at an angle with respect to a line that is parallel to the major dimension of the strip. The angle is arranged such that when the grip is wrapped about the sports implement, the guideline extends in a direction that is generally perpendicular to the longitudinal axis.
