ABSTRACT:
Techniques for defense against unwanted communications by striking back against the beneficiaries of the unwanted communications include identifying a communication channel to a beneficiary of an unwanted communication and sending a communication via the communication channel to the beneficiary such that the communication imposes a cost to the beneficiary. The cost to the beneficiary may be used to deter further unwanted communication from the beneficiary.
