Abstract: Methods, systems, and computer program products for online content referral are provided. A computer-implemented method may include issuing a challenge to an application interacting with a computer system to determine whether activity performed by the application is scripted, analyzing data associated with a result of the challenge to determine whether the result is at least partially correct, and computing a reputation score for the application based on the result of the challenge. A computer-implemented method also may include comparing the reputation score for the application to a threshold for identifying non-scripted activity, and determining that that the activity performed by the application is scripted when the reputation score for the application does not meet the threshold for identifying non-scripted activity.

Abstract: Methods, systems, and computer program products for online content referral are provided. A computer-implemented method may include receiving a request from an application, issuing a challenge to the application to determine a capability of the application, analyzing a result of the challenge to associate the application with an application type, determining whether the activity performed by the application is scripted, and classifying the activity as automated or semi-automated when it is determined that the activity is scripted.
