Social media support for movement

Before Saturday's demonstrations, the social movement had received significant support on social media, with 87.5% of likes on posts favorable to the mobilization, according to an analysis of 109,760 French-speaking posts published from October 10 to 17 on seven networks.

Foreign accounts and media reuse

Authorities acknowledged that some traffic was generated "to some extent" by foreign accounts, and videos of the violence that occurred on the fringes of the processions were widely reused by state media from Russia, Iran, Algeria, Turkey, and China. However, no attribution of foreign interference has been made public at this stage.

Participation numbers and incidents

According to the Ministry of the Interior, 550,000 people marched on Saturday, while organizers claimed 800,000 participants, including 110,000 in Paris. The mobilization was marked by incidents and looting in several cities.

Platform-specific content and analysis limits

The analysis by Agoratlas and the monitoring tool Visibrain found that among the posts that take a position, 87.5% of likes go to support for the social movement, 9.4% to opposition. Each platform has its own tone, with Bluesky being the most favorable network (47% of posts in support) and emphasizing repression. However, the study has its limits: it only analyzes text, leaving part of the video posts unexplored, and it stops before the evening's violence.

X platform and opposition content

X is an exception, where opposition posts (32.6%) exceed those of support (22.9%), in an indignant tone. However, even there, content favorable to the mobilization is more than twice as liked as hostile content. Agoratlas cites, among possible explanations, astroturfing, namely the mass production of fake content.

Domestic and foreign traffic

The movement generated significant traffic, "to some extent" by foreign accounts, admits a government source to 20 Minutes, but most of the online dialogue remains of domestic origin. The analyses must continue to isolate what constitutes foreign digital interference in the sense of Viginum, the French agency combating these phenomena.

Expert warnings and known influence

Evelyn Paris, an expert in European public policies and digital regulation, warns that the open-source elements available remain "sporadic." She notes, however, that known Iranian influence accounts participate in amplifying narratives of police violence, and that researchers and journalists also point to Russian and Algerian actors.

X platform vulnerabilities

Florent Lefebvre, scientific director of Agoratlas, states that X remains the platform most exposed to this type of maneuver: it is the one that moderates the least, and creating mass accounts there requires less effort than elsewhere. He also offers a hypothesis: by focusing mainly on X, where opposition to this movement was most audible, the government may have underestimated the scale of the mobilization.

Previous interference patterns

The precedent of September 10, 2025, invites caution. At that time, the Radio France Verification Agency had not detected any mass operations, but opportunistic reuse from Iran, Algeria, or Russia was noted. It is difficult to see clearly when talking about interference, but, on the other hand, one can already speak of appropriation: by Sunday, Donald Trump had denounced on his network Truth Social "the immigration of people from a completely different world [...] who have broken this country once so great."
