The project “Social Media Crime” aims at supporting stakeholders, first and foremost the Austrian Federal Ministry for the Interior (BM.I) including the Federal Crime Police Office (.BK) as a member of the project team, with a scientifically sound, case-related and practice-oriented, structured, interactive and flexible grid for the systematic classification and evaluation of social media crimes, which as a next step can facilitate the drafting of social media crime laws. Completing the consortium is the Austrian Center for Law Enforcement Sciences (ALES), which provides comprehensive legal expertise. Systematic literature reviews and in-depth requirements studies using qualitative interview guides with relevant stakeholders, as well as with other experts (e. g. security researchers, experts in the field of cybercrime, legal experts and international stakeholders), will be conducted. The project will result in a comprehensive taxonomy of social media crimes and related phenomena, respective practice-oriented and intuitive resources for stakeholders, knowledge about best practices, strategies and methods to prevent and counteract social media crimes, a sound legal evaluation including recommendations for legislation and an interactive collection of cases with the possibility to include new cases and relevant phenomena.
