Abstract: Described herein are devices and techniques for detecting an inbound message (e.g., text, voice, voicemail) directed from an identifiable message sender to one of a collection of message recipients (e.g., by telephone numbers). The message is selectively forwarded to the message recipient's communication devices in response to a reputation score of the identifiable message sender. The devices and techniques described herein are further adapted to automatically determine or otherwise update the reputation score of the identifiable message sender, for example, in response to previously detected incoming messages. User preferences can be provided to override one or more of forwarding and blocking of detected messages regardless of any automatically obtained reputation score.
