This paper offers a set of specific proposals for better describing harmful content online and for reducing the damage it causes, while protecting freedom of expression. The ideas are mainly meant for OSPs since they regulate the vast majority of online content; taken together they operate the largest system of censorship the world has ever known, controlling more human communication than any government. Governments, for their part, have tried to berate or force the companies into changing their policies, with limited and often repressive results. For these reasons, this paper focuses on what OSPs should do to diminish harmful content online. The proposals focus on the rules that form the basis of each regulation system, as well as on other crucial steps in the regulatory process, such as communicating rules to platform users, giving multiple stakeholders a role in regulation, and enforcement of the rules.
