Facebook said today it has removed hundreds of Facebook and Instagram accounts with links to an organization that peddled fake news.

The world’s fourth largest country with a population of more than 260 million, Indonesia is in an election year alongside Southeast Asia neighbors Thailand and the Philippines. Facebook said this week it has set up an “election integrity” team in Singapore, its APAC HQ, as it tries to prevent its social network being misused in the lead-up to voting as happened in the U.S.

This Indonesia bust is the first move announced since that task force was put in place, and it sees 207 Facebook Pages, 800 Facebook accounts, 546 Facebook Groups and 208 Instagram accounts removed for “engaging in coordinated inauthentic behavior.”

“About 170,000 people followed at least one of these Facebook Pages, and more than 65,000 followed at least one of these Instagram accounts,” Facebook said of the reach of the removed accounts.

The groups and accounts are linked to Saracen Group, a digital media group that saw three of its members arrested by police in 2016 for spreading “incendiary material,” as Reuters reports.

Facebook isn’t saying too much about the removals other than: “we don’t want our services to be used to manipulate people.”

In January, the social network banned a fake news group in the Philippines in similar circumstances.

Despite the recent action, the U.S. company has struggled to manage the flow of false information that flows across its services in Asia. The most extreme examples come from Myanmar, where the UN has concluded that Facebook played a key role in escalating religious hatred and fueling violence. Facebook has also been criticized for allowing manipulation in Sri Lanka and the Philippines, among other places.
