New Delhi (CNN Business)WhatsApp has a powerful platform in India. Sometimes too powerful.
Last year, a spate of lynchings triggered by viral hoax messages on its service put the company at the center of a debate about misinformation in the country, where it has more than 200 million users.
Now it’s bracing for India’s upcoming national elections, the biggest in the world.
WhatsApp is deploying artificial intelligence to clean up its platform ahead of the elections, in which more than 800 million Indians are eligible to vote. It’s also warning India’s political parties against spreading politically-motivated spam messages.
The Facebook ()-owned app is using AI tools to detect and ban accounts that spread “problematic content” through mass messaging, it said in a statement on Wednesday.
WhatsApp ‘s automated systems helped it ban more than 6 million accounts globally in the last three months. The systems monitor and flag suspicious behavior like bulk registrations of similar accounts and users that send a high volume of messages in a short amount of time.
“These efforts are particularly important during elections where certain groups may attempt to send messages at scale,” WhatsApp said.
The company has also warned Indian political parties that their accounts could be blocked if they try to abuse the platform during the campaign.
“We saw how parties tried to reach people over WhatsApp, and in some cases that involved attempting to use WhatsApp in a way that it was not intended to be used,” spokesperson Carl Woog told reporters in New Delhi, referring to a recent Indian state election.
“We have engaged with political parties to explain our firm view that WhatsApp is not a broadcast platform and is not a place to send messages at scale, and to explain to them that we will be banning accounts that engage in [suspicious] behavior,” he added.
Prime Minister Narendra Modi, a prolific user of social media himself, is seeking a second term in office when the country goes to the polls in the coming months. Facebook, Twitter ( ), and WhatsApp were used extensively by Modi’s Bharatiya Janata Party and its rivals during India’s last election in 2014, and are expected to play an even bigger role this time around.
But WhatsApp’s reputation in India, its biggest global market, has been dented by the mob violence and the misinformation spread on its platform.
The company last year attempted to stem fake rumors by labeling messages that are forwarded rather than composed by the sender, and by imposing limits on the number of simultaneous chats a message can be forwarded to.
It has also tried to raise awareness about misinformation by taking out newspaper, radio and television ads, targeting the hundreds of millions of Indians discovering the internet for the first time. The campaign, called “Share Joy, Not Rumors,” will be rolled out to other countries, including Brazil and Indonesia.
