Abstract: 【Purpose/significance】This study utilized the method of constructing user profiles to describe the characteristics of WeChat user privacy paradox behaviors. The aim is to provide social media platforms with a method of accurately understanding the differences in the characteristics of user privacy paradox behavior groups. This, in turn, can provide guidance for offering personalized privacy pro⁃ tection and targeted service strategies【. Method/process】With WeChat users as the research subjects, the study constructed a labeling system for WeChat user privacy paradox behavior groups starting from psychological preferences, drawing inspiration from the VALS2 user segmentation attitude scale. Data was obtained through questionnaire distribution. Factor analysis, cluster analysis, and discrimi⁃ nant analysis were used to analyze the WeChat user privacy paradox behavior through clustering. The characteristics of different user groups were visualized and presented【. Result/conclusion】The research indicates that the types of WeChat user privacy paradox behav⁃ ior groups can be divided into three categories: experience-oriented, mature and rational, and self-centered.【Innovation/limitation】 The study introduced a model for the user privacy paradox behavior group on social media. Future research will involve refining and validating the group image model and exploring its application in other scenarios.
