Brazil’s Supreme Court banned the popular messaging service Telegram, in a widening crackdown on what authorities describe as fake news and hate speech in the lead-up to presidential elections later this year.

Justice Alexandre de Moraes on Friday ordered internet providers and digital stores to block the app after repeated attempts by the federal police to get in touch with the service to remove content.

Telegram is “notoriously known for its stance of not cooperating with judicial and police authorities in several countries,” police wrote in their request to Moraes, which he cited in his decision. “It has become an open space for the proliferation of various content, including that with repercussions in the criminal area.”

The push to shut Telegram in Brazil is part of wide-reaching efforts to combat misinformation and falsehoods about the country’s electoral system. 

President Bolsonaro and his allies have pushed their online supporters to the London-based platform, after popular apps such as Twitter and Meta Platforms Inc.’s Facebook took down posts containing false information about Covid-19 and promoting unproven remedies. 

The far-right leader called the ban “unacceptable” late Friday evening, alleging it could affect some 70 million Brazilians who rely on the platform. He did not cite the source of user estimates. 

The government’s attorney general filed a precautionary measure in the Supreme Court challenging the order.   

Pavel Durov, Telegram’s founder and chief executive officer, said the ruling was simply the result of miscommunication, and that his platform was working to comply with the court’s orders.

“On behalf of our team, I apologize to the Brazilian Supreme Court for our negligence. We definitely could have done a better job,” Durov said in a statement published on his Telegram channel.

Durov asked the court to delay its ban to set up legal representation in Brazil and set up framework for future requests. 

While WhatsApp, which is owned by Facebook, continues to be more popular in Brazil, an August survey found that over half of smartphone users had downloaded Telegram.

The court gave companies five days to comply with the order or risk fines. On Saturday, Moraes said the company hadn’t fully complied with the court order and still had to exclude posts from President Jair Bolsonaro’s channel. The Supreme Court gave it 24 hours to comply with the ruling.

On Saturday morning Telegram was still available in Brazil via Google Play. Brazil’s authorities temporarily shut down YouTube in 2006, and WhatsApp in 2016.
