"The most extreme damage inflicted by social media can be seen in South Sudan. As documented in the chapter by Theo Dolan, social media in South Sudan has contributed to hatred and conflict among ethnic groups. Many investigators, including UN investigators, have warned that South Sudan's social media are triggering violence against ethnic groups. Since the beginning of the civil war in late 2013, social media has fuelled waves of hate speech that have provoked deadly violence and ethnic conflict in South Sudan, including massacres and other atrocities. In that sense, social media has become a new variation of the "hate radio" phenomenon that flourished in Rwanda before and during the 1994 genocide … Social media is also emerging as a powerful way to harass and intimidate the opponents of a regime or a political party. In this sense, it adds another weapon to the arsenal of a powerful regime that already has multiple weapons at its disposal. A regime can mobilize its supporters to use social media in a targeted way against its foes, or it can use its financial resources to create a fake army of fictional users on social media. In either case, it is tilting the playing field against its enemies. A targeted attack through social media can be more effective than the telephone threats or messages often deployed in the past. The use of social media can be more intimidating because it belittles the targeted person in front of a much bigger audience. The presence of this audience means that the attack is more damaging, more difficult to ignore and has the potential to mobilize large numbers of people against the victim … While social media is often used for anti-democratic purposes in Africa's authoritarian states, it has also been used as a force for reform, accountability and justice. It has helped to safeguard the fairness of elections. It has allowed greater scrutiny of potential threats, such as vote-rigging or violence, allowing citizens to be alerted when there is still a chance to prevent the worst abuses. It has put a spotlight on corruption and political wrongdoing, allowing activists to mobilize pressure on governments to resolve these long-neglected problems. In some cases, as it did in the Arab Spring, social media has played a role in toppling an authoritarian state. When an election was called in the small West African state of Gambia, where the dictator Yahya Jammeh had ruled for 22 years, opposition candidates had little access to state-controlled media. So the main opposition party created more than a dozen WhatsApp groups, allowing it to communicate with voters. Other forms of social media also proliferated. A leading independent group, the Gambia Youth and Women's Forum, discussed election issues on a public Facebook group with 55,000 members. The government blocked access to WhatsApp and eventually extended the shutdown to the entire internet, but Gambians used virtual private network (VPN) technology to bypass the shutdown. The opposition won the election and Jammeh was forced to flee the country." (Pages 419-423)
