European privacy watchdogs are planning to investigate data harvesting on social media platforms as Facebook’s data privacy scandal has invited scrutiny from regulators around the world.

Andrea Jelinek, who chairs a coalition of European data watchdogs called Working Party 29, announced on Wednesday that the organization was starting a task force to investigate social media and “develop a long-term strategy on the issue.”

“A multi-billion dollar social media platform saying it is sorry simply is not enough,” Jelinek said in a statement. “While Cambridge Analytica and Facebook are on top of everyone’s mind we aim to cast our net wider and think longterm.”

The company is also facing an investigation from the Federal Trade Commission.

Jelinek on Wednesday expressed support for similar probes from European authorities, like the one launched by the United Kingdom’s Information Commissioner’s Office (ICO), but added that regulators also need to take a broader look at the practice of data harvesting and its implications for internet users.

“This is why we are creating a Social Media Working Group,” Jelinek said. “What we are seeing today is most likely only one instance of the much wider spread practice of harvesting personal data from social media for economic or political reasons.”
