WhatsApp banned 100,000 accounts in Brazil during the Brazilian elections.

Facebook has created a “war room” to identify and eradicate misinformation, hate speech and other harmful content during Brazil’s election this month.

Facebook’s “war room” struggles to contain spam, misinformation and other political antics before the second round of elections in the largest country in Latin America.

“We have the latest technology to detect spam that identifies accounts with abnormal behavior so they can not be used to spread spam or misinformation,” a WhatsApp spokesman wrote in an e-mail. “We are also taking immediate legal action to prevent companies from sending bulk messages via WhatsApp and have already banned accounts associated with those companies. ”

Facebook has created a “war room” to identify and eradicate misinformation, hate speech and other harmful content during Brazil’s election this month. It is a test for social networking ahead of midyear elections in the US later this year. Although the company said it was able to prevent false information on its main social network, it had more trouble controlling bad behavior in WhatsApp, which is encrypted and virtually impossible to monitor.

On the news that agencies would be involved in scams to fire news without the consent of thousands of users, WhatsApp said on Friday that it is taking the charge seriously. “We are committed to enforcing WhatsApp policies equally and fairly to protect the users’ experience.”

WhatsApp has confirmed that it has blocked the account of Bolsonaro’s son, Flavio, for spam a few days ago. The company said it was unrelated to the allegations on Thursday. He also noted that he banned an account related to former Brazilian President Dilma Rousseff, a member of the Workers’ Party.
