Abstract

Communication abuse prevention techniques are described. In an implementation, a reputation level for a communication is determined based on relation information for a sender and an intended recipient of the communication. A challenge is invoked that is to be completed by the sender before the communication is sent. The challenge is selected based on the reputation level for the communication.
