General Background: Digital media has become a major arena for public protest, collective expression, political participation, and hashtag-based social movements. Specific Background: The #IndonesiaGelap movement emerged on social media as a public response to government regulations and policies perceived as unfavorable to society, and it circulated through platforms such as Twitter and TikTok. Knowledge Gap: The manuscript states that previous literature had not positioned #IndonesiaGelap as the main research object, while studies combining social movement analysis with network and survey approaches to identify negative communication remained limited. Aims: This study aimed to examine the distribution of information and communication networks around #IndonesiaGelap, identify actor roles, and analyze negative communication, hoax, and hate speech patterns using Network Society theory. Results: The study found that the social media network functioned as persuasive communication through unfiltered information and hate speech circulation. Actor networks appeared centralized, with driving actors forming sub-networks and anomalous accounts emerging within supporting clusters. Analysis of 64,816 comments on X showed 81% negative sentiment, 13% neutral sentiment, and 6% positive sentiment, with anger dominating negative comments at 22,482 comments. Novelty: The study focuses on #IndonesiaGelap through big data-based network analysis combined with survey logic. Implications: The findings support more transparent policy communication, dialogue-based governance responses, and deeper analysis of digital opinion leaders in contemporary social movements. Highlights: Big data mapping showed clustered actor roles and subgroups. Unfiltered information and hate speech circulated across platforms. Anomalous accounts appeared within supporting subclusters.
