Within weeks of Modi’s election, Zuckerberg and Chief Operating Officer Sheryl Sandberg both visited the nation as it was rolling out a critical free internet service that the government later curbed. Harbath and her team have also traveled there, offering a series of workshops and sessions that have trained more than 6,000 government officials.

As Modi’s social media reach grew, his followers increasingly turned to Facebook and WhatsApp to target harassment campaigns against his political rivals. India has become a hotbed for fake news, with one hoax story this year that circulated on WhatsApp leading to two separate mob beatings resulting in seven deaths. The nation has also become an increasingly dangerous place for opposition parties and reporters. In the past year, several journalists critical of the ruling party have been killed. Hindu extremists who back Modi’s party have used social media to issue death threats against Muslims or critics of the government.

On the night of Sept. 5, a Honda motorcycle pulled in front of the Bengaluru home of Gauri Lankesh, an outspoken critic of Modi who had been targeted by patriotic trolls on Facebook and other social media. As the Indian journalist was unlocking her gate, three bullets struck her in the head and chest, killing her. No arrests have been made.
