1. A method implemented by one or more processors, the method comprising:
monitoring a conversation between a bot and a communication participant, the conversation being initiated over a natural language communication channel, and the conversation being conducted using a natural language communication method that includes a dialogue of natural language communications;
determining that the communication participant is automated using a pre-defined adaptive interactive protocol that specifies a plurality of natural language linguistic transformations for the dialogue of natural language communications; and
in response to determining that the communication participant is automated, causing the conversation to be transitioned to a communication method that is different from the natural language communication method with which the conversation was initiated.
