This study explores the Twitter activities of Turkish supporters of the Islamic State of Iraq and Syria (ISIS) from 2019 to 2022, focusing on hashtag usage patterns. As a central part of ISIS's online strategy, hashtags are pivotal in disseminating propaganda, coordinating campaigns, and soliciting support. By analyzing 202,327 tweets, this research offers insights into thematic priorities and interconnections within ISIS-related discourse. Employing descriptive and network analyses, key findings reveal a steady increase in ISIS-supportive tweets, the emergence of clusters around aid and familial support, and distinct, unconnected hashtag groups reflecting various narratives. Hashtags related to financial aid, such as #saveprisoners and #elholcamp, emerge as central, highlighting a covert system of funding through social media and encrypted communication. This paper underscores the complexity of ISIS's digital influence in Türkiye, emphasizing the need for multifaceted countermeasures involving tech platforms, security forces, and media awareness campaigns to combat online extremist activities effectively.
