The purpose of this module is to provide a conceptual framework for small civil society organizations to address threats of harmful information including disinformation and online abuse such as harassment. These attacks spread hate and sway popular opinion using botnets, armies of trolls, and divisive fabricated content. They can target organizations, especially those engaged in political advocacy, with many tactics: activists and journalists are harassed, the reputations of advocacy organizations are tarnished, and public support for social causes is shifted. Complicating this picture, an organization’s ability to protect itself from harmful online information attacks can be impeded by the lack of a shared understanding of harm reduction across its own security, communications, human resources, and management functions.
