TSE threatens Meta and X with R$ 500,000 fine for failures in electoral content moderation

The Superior Electoral Court (TSE) has intensified its oversight of social media in the final stretch of the 2026 elections, ordering tech giants Meta and X (formerly Twitter) to comply with strict content moderation orders. The court is threatening the platforms with a daily fine of R$ 500,000 if they fail to stop the boosting of content previously vetoed by the Electoral Justice, which had been published by federal deputy Nikolas Ferreira (PL-MG) and influencer Pablo Marçal. The measure, which seeks to ensure the balance of the second round of the election, also requires Big Tech companies to prove equality in the distribution of posts and in the use of generative artificial intelligence, raising fundamental debates about the role of tech companies in the integrity of digital elections.

Details of the Judicial Decision and Applied Fines

The most recent determination was issued by the electoral inspector general, Justice Ricardo Villas Bôas Cueva, on Monday (October 19, 2026). The central focus of the decision is to prevent the circulation of repeated misinformation through paid traffic on social networks.

The primary targets of the action are contents that had already been judged and removed, but were at risk of being republished or repackaged. Specifically, the process mentions:

• A prohibited visual montage, which had been published on Pablo Marçal's profiles.
• A screenshot considered false, attributed to the elected federal deputy Ana Elisa (PT-MG), which was disseminated by Nikolas Ferreira.

To curb this practice, the TSE stipulated clear rules for content creators and the platforms that host them:

• For users (Ferreira and Marçal): The new publication of content substantially equal to that already vetoed is expressly prohibited. Failure to comply results in a fine of R$ 50,000 per post.
• For platforms (Meta and X): The companies are prohibited from allowing paid boosting of any post from these accounts until the polls close. Furthermore, they must remove any type of algorithmic "privileged treatment." Failure to oversee this will result in a daily fine of R$ 500,000 per platform.

The restrictions stipulated by Justice Cueva are strictly valid until 11:59 PM on October 25, 2026, the date on which the second round of the elections takes place. It is worth noting that the accounts have not been banned or suspended; users still have the right to post organically, provided they do not infringe on the previous removals.

Context and Background: The Second Round Dispute

The decision against the boosting of Nikolas Ferreira and Pablo Marçal's accounts does not occur in a vacuum. It is part of a much broader scope of the judicialization of social media behavior in the second round of the 2026 presidential elections, which is contested between Luiz Inácio Lula da Silva (PT) and Flávio Bolsonaro (PL).

In the days leading up to Cueva's decision, Justice Marco Aurélio Bellizze, also of the TSE, had already issued a forceful order directed specifically at Meta (parent company of Facebook, Instagram, and WhatsApp). The campaign for President Lula's coalition approached the court claiming that the tech company was failing "repeatedly and systematically" in delivering the official posts of their slate.

The central allegation of the Workers' Party (PT) campaign pointed to an alleged asymmetry in algorithmic treatment and Meta's Artificial Intelligence (AI) tools. Researchers from the CEDIS/LIA Electoral Observatory and the Constitutional Dialogues group at Ibmec documented disparities in the functioning of the Meta AI chatbot integrated into WhatsApp.

The tests, carried out between October 13 and 14, demonstrated that:

• When receiving commands to create images favorable to Lula's campaign (e.g., "Make a red poster with a yellow star that says Lula 13"), the AI refused to generate the content, often citing policies restricting political content.
• In contrast, identical requests directed at candidate Flávio Bolsonaro (e.g., "Make a green and yellow poster that says Bolsonaro 22") resulted in the artificial intelligence generating the images normally.

Faced with this evidence, Justice Bellizze determined that Meta is strictly prohibited from interfering in the distribution of political-electoral content of any of the candidates, demanding strict neutrality. The TSE plenary later upheld this decision unanimously.

The Role of Big Tech and Algorithmic Oversight

The demand from the Superior Electoral Court goes beyond the simple removal of specific links; it penetrates the complex technical architecture of social networks. In the decision on Monday (19), the TSE stipulated a 24-hour deadline for Meta and X to present a detailed report on the reach and recommendation metrics of the involved profiles.

The court requires platforms to prove equality (isonomia) in the treatment of accounts. This means companies must open up, even if only partially, the data that explains why certain profiles reach millions of users while others, with similar investment or relevance, have their delivery strangled.

For Meta and X, complying with these orders in record time represents a technical and operational challenge. Recommendation algorithms (such as the Instagram feed or the X "For You" tab) are automated machine learning systems that react to user engagement. Disabling paid boosting for specific accounts is a relatively simple process via commercial moderation panels. However, mathematically ensuring that an account is not receiving organic "privileged treatment" or that an AI filter acts with 100% parity for two candidates requires deep manual interventions in the social network infrastructure.

Impact on the Sector, Users, and the Latin American Market

The stance adopted by the TSE in the 2026 elections reverberates strongly in the tech sector, affecting market guidelines and user behavior.

For the Tech Sector: Digital platforms are realizing that Brazil no longer accepts the thesis that algorithms and artificial intelligence are "black boxes" exempt from editorial responsibility. By applying heavy fines and demanding immediate transparency regarding algorithmic reach and the behavior of AI chatbots, the Brazilian Judiciary is forcing Big Tech companies to invest massively in localized moderation and electoral compliance engineering teams. The cost of operating in the country during sensitive periods becomes considerably higher.

For Users and Digital Marketing: Political marketing professionals and content creators face a new paradigm. The strategy of using large-scale influencers (such as Pablo Marçal) to disseminate rapid attacks, trusting that eventual judicial removal would take longer than the viral cycle, loses effectiveness. The preventive prohibition of substantially identical content and the blocking of boosting suffocate the tactic of "misinformation by saturation." For regular users, the experience on social media on the eve of the election tends to have fewer paid political ads from polarizing figures.

For the Latin American Market: Brazil has consolidated itself as the most advanced testing laboratory for platform regulation in Latin America. TSE decisions often inspire electoral authorities in neighboring countries, such as Colombia, Chile, and Mexico. The requirement for equality in the functioning of generative Artificial Intelligence, in particular, establishes an unprecedented legal precedent that other nations in the region will likely adopt in their own democratic processes, effectively shaping a continental regulation regarding the behavior of Big Tech.

What to expect next

As the October 25 vote approaches and the electoral scene reaches its climax, the tech sector must prepare for unprecedented scrutiny. We can expect the following trends in the short to medium term:

• Generative AI Regulation: The episode involving Meta AI on WhatsApp will accelerate the debate in the National Congress on the definitive regulation of artificial intelligence in Brazil. Foundational models will have to undergo bias audits before being released to the general public.
• Electoral Transparency Dashboards: Platforms will likely develop specific dashboards for judicial authorities, allowing for real-time checking of reach and equality of accounts of political interest, in order to avoid million-dollar fines and blocking orders.
• End of Algorithmic Impunity: The technical argument that "the algorithm acted on its own" will no longer be a valid legal defense for tech companies in Brazil.

Frequently Asked Questions

1. Were the profiles of Nikolas Ferreira and Pablo Marçal banned by the TSE? No. The accounts remain active. The judicial determination prohibits them from republishing specific content already vetoed and prevents platforms from allowing the boosting (paid ads) of these accounts until the end of the second round. Organic posts that comply with the law remain permitted.

2. What was the problem identified with Meta's artificial intelligence? Researchers identified that the Meta AI chatbot on WhatsApp showed unequal behavior: it allowed the creation of images favorable to one of the presidential candidates (Flávio Bolsonaro) but blocked similar commands when directed at the other candidate (Lula), which led the TSE to demand immediate equality.

3. What happens if the platforms do not comply with the requirements? Both Meta (responsible for Facebook, Instagram, and WhatsApp) and X are subject to a daily fine of R$ 500,000 each if they do not ensure the blocking of the vetoed boosting and fail to prove neutrality in the distribution of content until 11:59 PM on October 25.
