A block on the social media platform X in Brazil came into effect early Saturday after Brazilian Supreme Court judge Alexandre de Moraes ordered its suspension late Friday after a months-long standoff with Elon Musk over disinformation in South America's biggest country. X decided to shut down its business operations in Brazil earlier this month rather than obey an order from the judge to block dozens of accounts being investigated over fake news or hate speech, an order Musk denounced as censorship.
