标题： Coordinated Activity Modulates the Behavior and Emotions of Organic Users: A Case Study on Tweets about the Gaza Conflict

摘要： 社交媒体已成为全球危机期间信息快速传播的关键渠道。 然而，这也为恶意行为者操纵叙事提供了途径。 本研究探讨了在加沙冲突期间，协调（恶意）实体与有机（常规）用户在推特上的互动动态。 通过对来自130多万用户的约350万条推文进行分析，我们的研究发现，协调用户对信息环境产生了显著影响，成功地将其内容传播到网络中：他们消息的很大一部分被有机用户采用和分享。 此外，研究记录了有机用户对协调内容的参与度逐步增加，这伴随着他们在后续交流中情绪极化表达的明显转变。 这些结果突显了对社交媒体平台上信息操控保持警惕和深入理解的必要性。 显示英文摘要

摘要： Social media has become a crucial conduit for the swift dissemination of information during global crises. However, this also paves the way for the manipulation of narratives by malicious actors. This research delves into the interaction dynamics between coordinated (malicious) entities and organic (regular) users on Twitter amidst the Gaza conflict. Through the analysis of approximately 3.5 million tweets from over 1.3 million users, our study uncovers that coordinated users significantly impact the information landscape, successfully disseminating their content across the network: a substantial fraction of their messages is adopted and shared by organic users. Furthermore, the study documents a progressive increase in organic users' engagement with coordinated content, which is paralleled by a discernible shift towards more emotionally polarized expressions in their subsequent communications. These results highlight the critical need for vigilance and a nuanced understanding of information manipulation on social media platforms.
