A method may include receiving a communication that is sent from a source over a network to a user. The method may also include categorizing the communication request. The categorization may include sending a first question communication that includes a first human-based interactive question over the network to the source. The categorization may also include receiving an answer communication over the network from the source and determining whether the answer communication correctly answers the first question communication. In response to determining that the answer communication correctly answers the first question communication, a second question communication that includes a second human-based interactive question may be sent over the network to the source instead of performing a first task with the received communication.
