Abstract
A method and apparatus tracks and blocks content requested by a first remote device for forwarding over a network to a second remote device. For a given content item, one or more usage identities are tracked. Usage identities may include any combination of one or more of a source identity, a content identity, and/or a destination identity. One or more thresholds associated with the tracked usage identities are applied to determine whether a request to forward content should be blocked; a threshold is a limit on the number of times a content item having a particular usage identity may be forwarded within a time period. Misuse of content-forwarding messaging services by spammers and the like may thereby be discouraged. In one embodiment, the invention may be employed as part of a content clipping service for forwarding content to mobile devices by way of SMS or another mobile messaging technology.
