Most users of South Korean AI character chat service Zeta are teenagers or younger, while Crack also has nearly half of its users in that age group, MobileIndex data showed. Operators say they separate adult content and apply identity checks, but questions remain about keeping conversations safe in general content. A National Assembly research report warned that constant access and ongoing interaction could worsen emotional dependence and excessive immersion among children and adolescents.

Users who find that smartphone contract or activation terms differ from what they were told, or suspect unfair sales practices, can file a direct report through a user-participation scheme and receive compensation if violations are confirmed. The Korea Communications Users Protection Association said reports must be filed within 14 days of activation. Only the subscriber can report, except parents reporting for minor children. Verified cases pay 50,000 won per report, limited to once per quarter and 200,000 won per year.
