Twitter Blocks Accounts of Raul Castro, Cuban State-Run Media Reuters HAVANA - U.S. social media company Twitter Inc. has blocked the accounts of Cuban Communist Party Leader Raul Castro, his daughter Mariela Castro and Cuba's top state-run media outlets, a move the Cuban Union of Journalists denounced as "massive censorship." Dozens of accounts of journalists for Cuban state-run media as well as the official account for the Communications Ministry were also blocked in the crackdown late Wednesday. Asked to comment on the suspensions, a Twitter spokesman said that the company's platform manipulation policies prohibit users artificially amplifying or disrupting conversations by using multiple accounts. The Cuban Union of Journalists said Twitter had suspended individual accounts in the past that had been recovered. .
