How China's biggest social network fights fake news
WeChat posts the top rumors every month... so it can debunk them

In China, WeChat has become a primary news source for Chinese internet users, just as Facebook in the West. And just like Facebook, fake news can spread rapidly on China’s biggest social network.
WeChat, the app that does everything
One of the ways WeChat deals with rumors? They post the top ten rumors every month on an official account -- to debunk them.
Another top rumor? That an article told people to stop using microwave ovens, because microwaved food gives people cancer (not true). Or that you can scan Chinese currency in the app QQ to see if they’re counterfeit (you can’t).
The debunking feature is apparently quite popular: The Rumor Filter account also operates a mini program, “WeChat rumor debunking assistant”, which WeChat claims is used by 300,000 people every day.

Here’s how the mini program works: The front page shows a feed of articles that have been debunked recently, with a search box at the top where you can search for terms and see if there are any debunked articles related to it.
