As a prime example of socio-technological transformation, social media services exert an enormous impact on modern culture. They are nowadays widely established for everyday life uses, but also during natural and man-made crises and political conflicts. For instance, Facebook was part of the Arabic Spring, facilitating the communication and interaction between participants of political protests. However, social media is not only used for good: Based on the notions of cultural violence and cultural peace, this chapter shows the potential for political fragmentation through social media, focusing on fake news and terrorism propaganda and their amplified dissemination through social bots. The chapter shows that regarding both the problematic aspects and the countermeasures, technology plays the role of an amplifier, enabling effects such as astroturfing and smoke screening, but also enhancing social bot detection. This chapter examines what these socio-technological transformations through social media imply in terms of legitimacy and trust.
