Meta's advertising systems are once again causing issues. On September 25, in Brazil, Meta temporarily suspended the use of advertising by the Facebook page of Luis Inácio Lula da Silva. He is campaigning for a fourth and final electoral term against Flávio Bolsonaro, son of former far-right president Jair Bolsonaro. His teams filed a complaint through the platform's systems and are awaiting explanations regarding the matter. A few weeks earlier, Amnesty International published a report in which it found the algorithmic systems of Meta to be ineffective in suspending advertisements aimed at spreading disinformation across its various platforms. These systems are designed to automatically detect and remove content that violates the company's policies, but the report suggests that they are not performing as intended. As the Brazilian population is scheduled to vote on October 4, outgoing president Lula warned against the risks of interference in public debate, according to Novara media, specifically highlighting the potential support that U.S. president Donald Trump could provide to Bolsonaro's candidacy. This concern is part of a broader discussion about the role of social media in shaping political discourse and the potential for foreign influence in elections. In Europe, where Meta has adopted an extensive interpretation of the European Union's regulation on transparency and targeting of political advertising (TTPA), the (dys)functioning of advertising tools is also a recurring issue for understanding the state of public debate. The TTPA aims to increase transparency and accountability in political advertising, but its implementation has led to challenges in how content is moderated and what is considered acceptable. At the beginning of September, a theater in Barcelona, Spain, saw Facebook and Instagram remove advertisements related to a theatrical adaptation of Virginia Woolf's A Room of One's Own, on the grounds that these works addressed "social issues." The company explained to the cultural institution that "any mention of civil rights, feminism, or social reforms are classified as 'social issues' by our automated systems" and therefore prevented from being broadcast, according to the Guardian. This incident relates to issues encountered in France, where the Fondation des Femmes has asked the company to broadcast one of its campaigns around International Women's Day on March 8. In France, since the early weeks following the implementation of the TTPA, non-governmental organizations specializing in topics as varied as the defense of women's rights, children's rights, or more broadly human rights have testified to Next that they observed a clear stiffening of the company's moderation practices regarding their advertising campaigns. A year earlier, on the contrary, a study by AI Forensics showed that the company's systems struggled to moderate political advertisements aimed at spreading pro-Russian narratives. This highlights the inconsistent performance of Meta's content moderation systems, which can sometimes be too strict or too lenient, depending on the context and the type of content being moderated.
