Replication Data for: The Momo Challenge: Measuring the extent to which YouTube portrays harmful and helpful depictions of a suicide game

Allegedly, the online suicide game "Momo Challenge" dares players to perform self-harming tasks and, ultimately, commit suicide. Journalists have criticized the large amount of YouTube videos in which YouTubers promote the challenge by passing on the phone numbers to their viewers. However, empirical knowledge about this and similar cyber threats is lacking. This data set was created to give insight into the reach of the Momo Challenge on YouTube, how users form communities around this video material, and to what extent it puts them at risk. It contains the results of a data crawl with NodeXL. Using the keywords ‘Momo Challenge English’, we ran the crawl for titles, descriptions, and tags during the turn of 2018/2019. We identified 487 videos, which we manually cleansed of videos unrelated to the challenge. The remaining data set consists of 209 videos.
