摘要：
2020年美国总统大选之后，2021年1月6日国会山发生暴力骚乱，美国民主价值观遭受前所未有的冲击。政治精英与边缘群体在社交媒体上散布的选举舞弊阴谋论和不实言论，为此次骚乱推波助澜。本研究探究了国会骚乱前7个月内Twitter上边缘内容与阴谋论的演变过程。我们分析了分享边缘内容的用户所开展的可疑协同活动，发现了从定向放大到人为制造共识等常见恶意操纵手段的证据。此外，我们梳理了边缘言论与阴谋论的时间演变脉络及二者关联，这些内容最终与#stopthesteal（停止窃选）话题标签及QAnon相关叙事合流，形成“选举被窃取”的论调。研究结果进一步表明，在重大社会事件期间，社交媒体平台为阴谋论的大范围传播提供了温床，这类传播可能引发线下协同行动与有组织暴力。
英文摘要：
The aftermath of the 2020 US Presidential Election witnessed an unprecedented attack on the democratic values of the country through the violent insurrection at Capitol Hill on January 6th, 2021. The attack was fueled by the proliferation of conspiracy theories and misleading claims about the integrity of the election pushed by political elites and fringe communities on social media. In this study, we explore the evolution of fringe content and conspiracy theories on Twitter in the seven months leading up to the Capitol attack. We examine the suspicious coordinated activity carried out by users sharing fringe content, finding evidence of common adversarial manipulation techniques ranging from targeted amplification to manufactured consensus. Further, we map out the temporal evolution of, and the relationship between, fringe and conspiracy theories, which eventually coalesced into the rhetoric of a stolen election, with the hashtag #stopthesteal, alongside QAnon-related narratives. Our findings further highlight how social media platforms offer fertile ground for the widespread proliferation of conspiracies during major societal events, which can potentially lead to offline coordinated actions and organized violence.
