Connectivity of online hate multiverse. We counted all links between hate clusters on different social media platforms between June 1, 2019 and March 23, 2020. Each edge shows percentage of such links from hate clusters on the outbound platform to hate clusters on the inbound platform. Some platform pairs feature zero such links, hence no arrow. Although content moderation prevents users on some platforms (e.g., Facebook) from linking to some unmoderated platforms (e.g., 4Chan), users can access such content—and direct other users to it—by linking to a hate cluster on a third platform (e.g., Telegram) that then links to the unmoderated platform.
