ABSTRACT Vigilantism is defined as collective coercive practices carried out by non-state actors and intended to enforce norms (social or judicial) or to act directly to enforce such actors’ views of the law. Vigilantes are involved in both societal control and the fight against crime. In this article, we analyse how societal vigilantes use digital media (Facebook) to act on immigration, national identity, ethnic boundaries, and cultural values in the province of Quebec, Canada. We show how social media practices entail performative effects that should not be considered exclusively in terms of physical expression, such as gatherings of dispersed constituencies, as in, for example, the Arab Spring, but also in relation to the construction of boundaries and increased polarisation between social groups. These latter effects have real consequences, such as separating one element of the population (Muslims) from the moral obligation social groups have towards each other in society.

“警惕的公民”与数字警戒：魁北克最右端的案例研究

摘要警惕性被定义为由非国家行为者执行的集体强制性实践，旨在执行规范（社会或司法）或直接采取行动以实施此类行为者的法律观点。治安警察参与社会控制和打击犯罪。在本文中，我们分析了社会治安维持者如何使用数字媒体（Facebook）对加拿大魁北克省的移民，民族认同，种族边界和文化价值采取行动。我们展示了社交媒体实践如何带来表演效果，这些效果不应该仅仅从物理表达的角度来考虑，例如在“阿拉伯之春”中分散的选区的聚集，而且还涉及边界的构建和极化的加剧社会群体之间。后面这些影响会带来实际的后果，
