Whistleblower Frances Haugen told that a further study into Facebook’s lack of controls to prevent misinformation and abuse in languages other than English is likely to leave people “even more shocked ” about the possible harms inflicted by the social media company.

Haugen, a former product manager at Facebook’s Meta Platforms Inc (FB.O), spoke at the Reuters Next conference.

She left in May with tens of thousands of internal documents, which she disclosed to the Wall Street Journal.

In September, a series of articles revealed how the company knew its applications were spreading contentious information and harming the mental health of some young users.

According to internal papers and interviews with former employees, Facebook also realized it had too few people with the appropriate language skills to identify harmful posts from users in a number of developing countries.

People who use the platform in languages other than English are using a “raw, dangerous version of Facebook,” Haugen said.

She continued: the company should be required to disclose which languages are supported by its tech safety systems, otherwise “Facebook will do … the bare minimum to minimize PR risk,” she said.

Haugen also said that the social media company knew it could introduce “strategic friction” to make users slow down before re-sharing posts, such as requiring users to click a link before they were able to share the content. But she said the company avoided taking such actions in order to preserve profit.
