Cyberbullying Mitigation by a Proxy Persuasion of a Chat Member Hijacked by a Chatbot

Abstract

In this study, to mitigate cyberbullying in communication tools, we propose a method in which a chatbot pretending to be a member of a chat group defends the victim by proxy without permission (i.e., hijacking and proxy persuasion). An experiment was conducted to verify the effectiveness of the proposed method, the results of which showed that it increases the defending behavior of a user who was temporarily hijacked by the chatbot. However, compared with the existing method, the proposed method was found to have a problem with the continued use of the system.
