A computer-implemented method, including identifying user subscriptions that meet at least one criterion of a plurality of criteria for detecting subscriptions that are no longer active, classifying the user subscriptions into a first group and a second group, where user subscriptions in the first group have at least one context factor associated with the at least one criterion, matching the user subscriptions of the second group with data of unavailable users to produce a third group of user subscriptions, where the user subscriptions of the third group are successfully matched with some of the data of unavailable users.
