SAO PAULO (AP) Brazil started blocking Elon Musks social media platform X early Saturday, making it largely inaccessible on both the web and through its mobile app after the company refused to comply with a judges order.

X missed a deadline imposed by Supreme Court Justice Alexandre de Moraes to name a legal representative in Brazil, triggering the suspension. It marks an escalation in the monthslong feud between Musk and de Moraes over free speech, far-right accounts and misinformation.

To block X, Brazils telecommunications regulator, Anatel, told internet service providers to suspend users access to the social media platform. As of Saturday at midnight local time, major operators began doing so.

De Moraes had warned Musk on Wednesday night that X could be blocked in Brazil if he failed to comply with his order to name a representative, and established a 24-hour deadline. The company hasnt had a representative in the country since earlier this month.

Elon Musk showed his total disrespect for Brazilian sovereignty and, in particular, for the judiciary, setting himself up as a true supranational entity and immune to the laws of each country, de Moraes wrote in his decision on Friday.

The justice said the platform will stay suspended until it complies with his orders, and also set a daily fine of 50,000 reais ($8,900) for people or companies using VPNs to access it.

In a later ruling, he backtracked on his initial decision to establish a 5-day deadline for internet service providers themselves and not just the telecommunications regulator to block access to X, as well as his directive for app stores to remove virtual private networks, or VPNs.

The dispute also led to the freezing this week of the bank accounts in Brazil of Musks satellite internet provider Starlink.

Brazil is one of the biggest markets for X, which has struggled with the loss of advertisers since Musk purchased the former Twitter in 2022. Market research group Emarketer says some 40 million Brazilians, roughly one-fifth of the population, access X at least once per month.

This is a sad day for X users around the world, especially those in Brazil, who are being denied access to our platform. I wish it did not have to come to this it breaks my heart, Xs CEO Linda Yaccarino said Friday night, adding that Brazil is failing to uphold its constitutions pledge to forbid censorship.

X had posted on its official Global Government Affairs page late Thursday that it expected X to be shut down by de Moraes, simply because we would not comply with his illegal orders to censor his political opponents.

When we attempted to defend ourselves in court, Judge de Moraes threatened our Brazilian legal representative with imprisonment. Even after she resigned, he froze all of her bank accounts, the company wrote.

X has clashed with de Moraes over its reluctance to comply with orders to block users.

Accounts that the platform previously has shut down on Brazilian orders include lawmakers affiliated with former President Jair Bolsonaros right-wing party and activists accused of undermining Brazilian democracy. Xs lawyers in April sent a document to the Supreme Court in April, saying that since 2019 it had suspended or blocked 226 users.

In his decision Friday, de Moraes cited Musks statements as evidence that Xs conduct clearly intends to continue to encourage posts with extremism, hate speech and anti-democratic discourse, and to try to withdraw them from jurisdictional control.
