South Korea fines Meta £11.5m for illegally collecting Facebook user information

South Korea’s privacy watchdog has fined social media company Meta 21.6 billion won (£11.5 million) for illegally collecting sensitive personal information from Facebook users and sharing it with thousands of advertisers.

The information included data about their political views and sexual orientation.

It was the latest in a series of penalties against Meta by South Korean authorities in recent years as they increase their scrutiny of how the company, which also owns Instagram and WhatsApp, handles private information.

Following a four-year investigation, South Korea’s Personal Information Protection Commission concluded that Meta unlawfully collected sensitive information about around 980,000 Facebook users, including their religion, political views and whether they were in same-sex unions, from July 2018 to March 2022.

It said the company shared the data with around 4,000 advertisers.

South Korea’s privacy law provides strict protection for information related to personal beliefs, political views and sexual behaviour, and bars companies from processing or using such data without the specific consent of the person involved.

The commission said Meta amassed sensitive information by analysing the pages the Facebook users liked or the advertisements they clicked on.

The company categorised ads to identify users interested in themes such as specific religions, same-sex and transgender issues, and issues related to North Korean escapees, said Lee Eun Jung, a director at the commission who led the investigation on Meta.

“While Meta collected this sensitive information and used it for individualised services, they made only vague mentions of this use in their data policy and did not obtain specific consent,” Ms Lee said.

Ms Lee also said Meta put the privacy of Facebook users at risk by failing to implement basic security measures such as removing or blocking inactive pages.

As a result, hackers were able to use inactive pages to forge identities and request password resets for the accounts of other Facebook users.

Meta approved these requests without proper verification, which resulted in data breaches affecting at least 10 South Korean Facebook users, Ms Lee said.

In September, European regulators hit Meta with more than 100 million dollars (£77 million) in fines for a 2019 security lapse in which user passwords were temporarily exposed in an un-encrypted form.

Meta’s South Korean office said it would “carefully review” the commission’s decision, but did not immediately provide more comment.

In 2022, the commission fined Google and Meta a combined 100 billion won (£55.5 million) for tracking consumers’ online behaviour without their consent and using their data for targeted advertisements, in the biggest penalties ever imposed in South Korea for privacy law violations.

The commission said then that the two companies did not clearly inform users or obtain their consent to collect data about them as they used other websites or services outside their own platforms.

It ordered the companies to provide an “easy and clear” consent process to give people more control over whether to share information about what they do online.

The commission also hit Meta with a 6.7 billion won (£3.7 million) fine in 2020 for providing personal information about its users to third parties without consent.
