 Using the social networking service TikTok, fans of K-pop music disrupted science for President Trump's June rally in Tulsa. They also trick social media algorithms to slow the spread of anti-black lives matter hashtags. These examples illustrate how powerful social media has become in digital activism, says Michigan State Associate Professor Anjana Susarla. First, social media gives an opinion-making role to a few influencers with large followings. Secondly, people tend to engage with like-minded people on social media, a phenomenon known as homophily. Together, these mechanisms enable a video or a tweet to go viral, creating a situation that's impossible for the targeted companies or individuals to ignore. K-pop fans may have also flooded the Trump campaign with bad data, which could interfere with their voter turnout models and targeted online advertisements. The success of the TikTok teens campaign also shows how it's relatively easy for a group including foreign actors to interfere in the political process by using social media.
