As technology continues to dominate various aspects of life in the current 5.0 era, social media has become a key driver of human activities. These platforms provide spaces for free and easy interaction, particularly among the youth, but also raise significant concerns regarding communication ethics.

This article reviews literature on communication ethics in social media, emphasizing its impact on online civility, the mental health of the youth, and the ethical challenges in online communication in Indonesia. The findings suggest a need for policies promoting ethical communication on social media and increased awareness among the younger generation. The study advocates for educational initiatives focusing on sustaining and continuously applying communication ethics.
