Meta will face a hefty fine over advertising practices that violate user privacy, Norway’s data protection authority has said, unless the Facebook and Instagram owner takes action to comply with the law.

Norwegian regulator Datatilsynet says that behavioural advertising – a common marketing model that profiles users by collecting information such as their physical locations, among other data – without consent is illegal.

Because of this, Datatilsynet is imposing a “temporary ban” of such practices on Facebook and Instagram.

During the ban, which starts on August 4, Meta risks a fine of up to one million Norwegian kroner (£76,000) each day.

The ban will “last for three months, or until Meta can show that it complies with the law”, Datatilsynet said.

This decision “does not ban Facebook or Instagram in Norway”, Tobias Judin, the Norwegian Data Protection Authority’s international department head, stated in a release.

“The purpose is rather to ensure that people in Norway can use these services in a secure way and that their rights are safeguarded.”

In a statement sent to The Associated Press (AP) on Monday, Meta said the company will review Datatilsynet’s decision – and added that there is “no immediate impact” to its services.

“The debate around legal bases has been ongoing for some time and businesses continue to face a lack of regulatory certainty in this area,” Meta said.

“We continue to constructively engage with the Irish (Data Protection Commission), our lead regulator in the EU, regarding our compliance with its decision.”

Norway is not a member nation of the European Union, but is included in the European Economic Area (EEA).

In Monday’s announcement, Datatilsynet pointed to a December decision from the Irish DPC, which ordered Meta to bring behavioural advertising in line with European law by April.

The regulator also nodded a recent judgment from the EU’s top court, which outlined how Meta’s practices still did not comply with the law.

“Nonetheless, Meta continues its practices,” Mr Judin told The AP over email.

“Considering the recent legal developments and Meta’s inaction, we consider it urgent to intervene. If not, we fear that Meta would continue delaying compliance.”

A behavioural advertising ban beyond Norway is possible.

Datatilsynet says it may take the matter to the European Data Protection Board, which could extend the three-month ban and lead to wider implications across the continent.

Meta has been under fire over data privacy for some time.

In May, for example, the EU slapped Meta with a record 1.3 billion dollar (£1 billion) fine and ordered it to stop transferring users’ personal information across the Atlantic by October.

And the tech giant’s new text-based app, Threads, has not rolled out in the EU due to privacy concerns.
