Myanmar Groups Slam Facebook CEO for Downplaying Problems Six civil society groups in Myanmar claim Mark Zuckerberg distorted his company's role in stopping Facebook Messenger posts from inciting violence in the country.

Civil society groups in Myanmar are not pleased with Mark Zuckerberg.

In a Thursday letter, they slammed the Facebook CEO for a Vox Media interview in which they believe Zuckerberg glossed over Facebook's problems in the country. Zuckerberg claimed his company stopped attempts to incite violence between Myanmar's Muslim and Buddhist groups over Facebook Messenger.

"Our systems detect that that's going on. We stop those messages from going through," Zuckerberg said.

Groups in Myanmar, however, claim Facebook failed to quickly notice the problem last September, when the incident occurred. At the time, bad actors encouraged violence over Facebook Messenger with content that circulated for more than four days, possibly reaching hundreds of thousands of people.

Only when the civil society groups alerted Facebook about the abuse did the social media giant intervene, their letter says. "In your interview, you refer to your detection 'systems.' We believe your system, in this case, was us -- and we were far from systematic," the letter adds.

Although Facebook eventually stopped the abuse, by then the offending messages had caused widespread fear and at least three violent incidents, according to the groups. Making matters worse is that Facebook is ill-equipped to stop future attempts to incite violence over the platform, they add.

"As far as we know, there are no Burmese-speaking Facebook staff to whom Myanmar monitors can directly raise such cases," their letter reads. "We were lucky to have a confident English speaker who was connected enough to escalate the issue."

So far, Facebook hasn't commented on the letter. But criticism of the company's role in fanning ethnic violence in Myanmar is only growing. Last month, United Nations officials said Facebook had become a tool to spread violent messages in the country.

"Hate speech and incitement to violence on social media is rampant, particularly on Facebook," said UN human rights investigator Marzuki Darusman. "To a large extent, it goes unchecked."

Facebook is well aware of the problems and is trying to solve them, according to Zuckerberg. One company executive claims his teams are losing sleep over the issue.

The civil society groups in Myanmar say they want to work with Facebook to crack down on the abuse. But so far, they've only engaged with Facebook's policy team, and not the product or engineering divisions. Attempts at greater collaboration have also gone unanswered, they claim.

"The risk of Facebook content sparking open violence is arguably nowhere higher right now than in Myanmar," their letter adds.

The letter comes from six groups, including the IT innovation lab Phandeeyar, the Myanmar ICT for Development Organization, Burma Monitor, the Center for Social Integrity, Equality Myanmar and Myanmar Human Rights Educator Network.
