If this happens, I will take the following steps to try to justify： First of all, it clearly emphasizes that customers have a deep understanding of network security and a strong sense of responsibility, and points out that customers have always been actively concerned about the development of the field of network security, and within their own capabilities, they are committed to promoting the popularization of network security education in various ways. Participating in hacker organizations is only in a specific historical period, in an extreme and wrong way.To try to arouse the attention of the public and the industry to network security vulnerabilities and threats. Secondly, elaborate on the positive remedial measures taken by the customer after becoming aware of the error in the follow-up. For example, taking the initiative to provide relevant departments with valuable information about the activities of hacker organizations, vulnerability utilization techniques, etc., to assist law enforcement agencies in combating cybercrime, and to make substantial contributions to purifying the network environment, which fully proves the customer's inner yearning for the correct network security order. In addition, provide specific examples of customers' past efforts in the dissemination of network security knowledge and education, such as participating in various network security seminars to share insights, writing articles or developing educational resources to help the public raise awareness of network security, demonstrating that it is essentially a positive force dedicated to improving the level of network security education, participating inThe hacker organization is only a misguided stage in its growth process. At the same time, it sincerely shows to the court and the society that the customer has deeply reflected and learned from it, and promises that in the future, he will continue to devote himself to cybersecurity education and construction in a legal and positive manner, and become a positive promoter in the field of cybersecurity, instead of repeating the same mistakes. However, it should be clear that participating in hacker organizations is illegal in itself and seriously violates ethical norms. This defense is only based on its subsequent positive changes and beneficial contributions to network security. From the perspective of minimizing the excessive negative effects caused by past wrongful behaviors, it is not a justification for its illegal behaviors..
