Brazil’s electoral court has ordered Nikolas Ferreira, a conservative federal deputy, and the online influencer Pablo Marçal to stop posting false or unlawful election content, such as misuse of artificial intelligence, until voting ends on Sunday 25 October. Each post that breaks the order carries a R$100,000 fine (about US$20,000 at 4.97 reais per dollar), Folha de S.Paulo reported.
Both men back Flávio Bolsonaro, senator for Rio de Janeiro, in the Brazil election 2026 runoff against Luiz Inácio Lula da Silva, Brazil’s president. The ruling lands two days before a vote that matters to US investors holding Brazilian assets and to Washington’s trade ties with Latin America’s largest economy.
What the Electoral Court Ordered
Ricardo Villas Bôas Cueva, the court’s electoral inspector-general, issued the order on Friday 23 October, Folha reported. It bars false content, misuse of artificial intelligence and the use of children’s images by Ferreira, a deputy for the PL party from Minas Gerais, and Marçal for every post made until the end of the runoff voting.
Cueva also told Meta, the owner of Instagram, Facebook and Threads, and the social network X to file reports on how the two accounts spread, every six hours on the eve of the vote and on election day, according to Folha. Each platform faces a R$500,000 fine (about US$100,000) for failing to comply.
Why the Court Acted Now
The decision answers a complaint by Lula’s re-election coalition, Brasil Pronto pra Mais, which argues that posts by the two allies reach users who do not follow them. Its lawyers pointed to platform data showing wide circulation of the posts, Folha reported.
Cueva said that data did not clearly identify how the distribution worked or prove unlawful favouring by the platforms’ algorithms, according to Folha. He cited earlier rulings instead: in under three weeks the court had made at least six decisions on removing posts for disinformation, quotes taken out of context or the use of children’s images.
An Earlier Order on 19 October
The new order follows an earlier one of 19 October. That ruling barred Ferreira and Marçal from republishing content the court had already ordered removed, with a R$50,000 fine (about US$10,000) per breach, Congresso em Foco reported.
Meta and X were also told then to block paid promotion of the two accounts until 23:59 on 25 October, under fines of R$500,000 a day each. Our earlier report covered how Meta and X had 24 hours to explain their feeds on political content, a day before this ruling.
What It Means for You
If you hold Brazilian stocks, bonds or US-listed Brazilian shares, rulings on online speech add to election-week uncertainty. The court is signalling that it will police social media closely until the polls close.

If you use Instagram, Facebook or X, the case shows a Brazilian court setting rules for how US platforms handle a foreign election. Whether such orders change what voters see on Saturday and Sunday is the open question.

What Is Not Known
It is not yet public which future posts the court may find in breach, or what the reports will show. The reports from Meta and X are due every six hours, and the sources reviewed do not say whether either man will appeal.
Minister Cueva said the platform data did not show unlawful favouring by the algorithms, so the case rests on the posts themselves.
