The era of plausible deniability is over
Em um momento em que as fronteiras entre liberdade de expressão e responsabilidade digital se tornam cada vez mais porosas, o Supremo Tribunal Federal do Brasil decidiu que as grandes plataformas tecnológicas não podem mais se esquivar das consequências do que circula em seus espaços. A partir de uma decisão histórica, empresas como Meta, Google e TikTok têm sessenta dias para demonstrar que são capazes de governar o que criaram — ou arcar com as consequências civis de não fazê-lo. É um momento em que o direito tenta alcançar a velocidade da tecnologia, e em que a sociedade pergunta quem, afinal, é responsável pelo que acontece no espaço público digital.
- O STF derrubou a proteção legal que permitia às plataformas ignorar conteúdos ilegais enquanto não houvesse ordem judicial — agora, a notificação já basta para exigir a remoção.
- A lista de conteúdos proibidos é extensa e urgente: exploração sexual infantil, violência contra crianças, discurso de ódio, terrorismo, incitação ao suicídio e atos antidemocráticos estão todos na mira.
- A decisão gerou tensão interna no tribunal: enquanto alguns ministros celebraram o fim da impunidade digital, outros alertaram que delegar a moderação a empresas privadas pode silenciar vozes legítimas.
- As plataformas têm até o final de agosto para construir sistemas, contratar equipes e nomear representantes legais no Brasil — ou enfrentar processos civis por danos causados por seus usuários.
O Supremo Tribunal Federal do Brasil proferiu na quinta-feira uma decisão que redefine as regras do jogo para as grandes empresas de tecnologia. Meta, Google, TikTok e outras plataformas têm agora sessenta dias para implementar novos mecanismos de controle de conteúdo — ou responder civilmente pelos danos causados por seus usuários.
A decisão encerra um ciclo iniciado em junho do ano passado, quando o STF começou a questionar o Artigo 19 do Marco Civil da Internet, lei de 2014 que protegia as plataformas de responsabilidade enquanto não houvesse ordem judicial de remoção. Os ministros concluíram que esse modelo era insuficiente e incompatível com direitos fundamentais. A partir de agora, basta uma notificação para que a plataforma seja obrigada a agir.
O rol de conteúdos que devem ser removidos é amplo: material de exploração sexual infantil, vídeos de violência contra crianças, posts que incentivem o suicídio ou o tráfico de pessoas, discurso de ódio, terrorismo e atos antidemocráticos. As empresas também deverão manter um representante legal em território brasileiro para receber intimações e demandas judiciais.
A decisão não foi unânime. O ministro Alexandre de Moraes defendeu que plataformas com posições políticas e econômicas devem ser tratadas como qualquer outro agente sujeito à lei. Já o ministro André Mendonça alertou para o risco de autocensura ao transferir a moderação para empresas privadas. O ministro Flávio Dino rebateu com pragmatismo: abra qualquer rede social, disse ele, e você encontrará dezenas de crimes — não há efeito silenciador a temer.
O texto final da decisão será aprovado na quarta-feira e passará a orientar todos os casos de remoção de conteúdo em tramitação nos tribunais brasileiros. O prazo começou a correr em 27 de junho de 2025. Para o setor tecnológico, a mensagem é clara: a era da negação plausível chegou ao fim.
Brazil's Supreme Court handed down a sweeping decision on Thursday that reshapes how technology companies must police their platforms. The justices gave the tech giants sixty days to put new rules into effect—a deadline that will force Meta, Google, TikTok, and others to fundamentally change how they handle illegal content posted by their users.
The ruling emerged from a case the Court had been wrestling with since last June, when it first declared that platforms could no longer hide behind a legal shield that had protected them from responsibility for what their users posted. That old protection came from Article 19 of Brazil's Internet Civil Rights Law, a 2014 statute designed to safeguard free expression by saying platforms weren't liable for user content unless a judge ordered them to take it down. The Court found that framework inadequate. It violated fundamental rights and democracy itself, the justices concluded. Now, without waiting for Congress to write new legislation, the Court is imposing its own standard: platforms must answer for the damage their users cause.
The list of content that must go is specific and sweeping. Platforms must remove material depicting child sexual exploitation and abuse. They must take down videos showing violence against minors, or content that could push children toward self-harm or mental illness. They must delete posts promoting anti-democratic acts, terrorism, hate speech based on race or religion, incitement to suicide, trafficking, and crimes against women. The companies have been ordered to do this after receiving notice—they don't need to wait for a court order anymore. And they must maintain a legal representative inside Brazil to receive court documents and demands.
The decision did not pass without tension. Minister Alexandre de Moraes argued that tech platforms are neither neutral nor transparent—they have political and economic positions, he said, so they should face the same accountability as anyone else who breaks the law. He cited Pope Leo XIV's call for "disarming artificial intelligence," suggesting the platforms wield power that demands restraint. But Minister André Mendonça worried the ruling would chill free speech. By outsourcing content moderation to private companies, he said, the Court was creating a chilling effect on public expression. Minister Flávio Dino pushed back hard. Open any social network, he said, and you'll find fifty crimes. There's no chilling effect—if anything, he wished there were.
The final text of the ruling will be formally approved on Wednesday, and it will become the legal standard for all content removal cases working their way through Brazilian courts. The clock started ticking on June 27, 2025, when the Court published its decision. That means platforms have until late August to show they've built the systems, hired the staff, and written the policies to comply. If they don't, they face civil liability—they can be sued for the harm their users caused, and they'll have to pay damages. The Court has essentially told the tech industry that the era of plausible deniability is over.

La Conversación del Hearth Otra perspectiva de la historia
Why did the Court feel it had to act now, rather than wait for Congress to pass a new law?
Because the old law was broken. Article 19 created a loophole so wide that platforms could host almost anything and claim they weren't responsible. The Court saw that as incompatible with protecting democracy and fundamental rights. They couldn't wait.
But doesn't this put enormous pressure on the platforms to over-moderate? Won't they just delete things to be safe?
That's exactly what Mendonça worried about. And he has a point. When you make a company liable for what users post, the incentive is to remove first and ask questions later. Dino's counter-argument was that the platforms aren't doing enough now—that the problem isn't over-moderation, it's under-moderation. The streets are full of illegal content.
What about the requirement to keep a legal representative in Brazil?
That's the enforcement mechanism. Right now, if a Brazilian judge issues an order, the company can claim it didn't receive it, or it got lost in translation, or it went to some office in another country. Now there's someone here, in Brazil, who has to answer for the company. It makes evasion much harder.
How does this compare to what Europe or the United States has done?
Europe's Digital Services Act is similar in spirit but different in execution—it's a law passed by elected representatives, not a court ruling. The U.S. has Section 230, which is the opposite: it shields platforms from liability. Brazil is taking a middle path, but it's doing it through judicial decree rather than legislation.
What happens if a platform just ignores the deadline?
They get sued. Users, victims, their families—anyone harmed by illegal content the platform didn't remove can sue for damages. The liability becomes real and financial. That's the teeth in this ruling.
