This paper analyses the policy and legal implications related to the promotion of quality online content that supports and reinforces institutional and societal efforts to prevent, counteract and deflate radical discourses leading to violent behaviour. This analysis will focus on content disseminated via online platforms or intermediaries, and in particular on the intermediaries providing hosting services, who offer a relatively wide range of services for online storage, distribution, and sharing; social networking, collaborating and gaming; or searching and referencing.
