"The court walked back on its ban after Telegram made several changes to help keep misinformation at bay in the country, which includes removing classified information shared by Brazilian President Jair Bolsonaro and deleting accounts belonging to Allan dos Santos, an activist and Bolsonaro supporter accused of spreading disinformation."

Well that didn't last long but it appears to have only been lifted after Telegram agreed to censor some information and accounts. The fact that the ban occurred because of lack of monitoring of a mailbox is a real face-palm moment and a bit disconcerting too! "Supreme Court Judge Alexandre de Moraes, an opponent of President Bolsonaro, ordered the ban on the app, which wound up lasting just two days. As Telegram CEO Pavel Durov explains, his company didn’t take action sooner because they were checking the wrong email inbox and failed to see the messages from Brazil’s Supreme Court."
