A flexible, extensible, and dynamically configurable anti-spam facility that operates on a general quanta of data (such as for example a Short Message Service message, a Multimedia Message Service message, an Internet Protocol Multimedia Subsystem message, a Wireless Application Protocol stream, an Electronic Mail message, an Instant Messaging exchange, streaming (audio, video, etc.) data, etc.), innovatively analyzes various attributes of same (such as for example originating address and destination address), and—when an instance of spam is identified—performs one or more remediation activities (such as for example updating a blacklist, updating a greylist, dropping a message, issuing an alert, etc.). The facility may optionally leverage the capabilities of a centrally-located Messaging Inter-Carrier Vendor.
