On August 12, Austrian advocacy group NOYB filed a complaint against social networking platform X, accusing the company of violating EU privacy regulations by using users' personal data to train its artificial intelligence (AI) without their consent.

The group, led by privacy activist Max Schrems, has filed General Data Protection Regulation (GDPR) complaints with regulators in nine EU countries to increase pressure on the Irish Data Protection Commission (DPC).

The Irish Data Protection Commission, the main regulator in the EU for most American Internet companies, has sought an order against X to suspend or restrict its processing of user data for the development, training or improvement of AI systems.

Last week, in an Irish court hearing, X agreed not to use personal data collected from EU customers to train its AI system until users have the right to withdraw their consent. However, NOYB said that the DPC's complaint focused on mitigation measures and X's lack of cooperation, rather than the legality of the data processing itself.

Max Schrems said in a statement: "We want to ensure that Twitter (X) fully complies with EU law, at least including obtaining user consent in this case."

Last week, an Irish court ruled that X only provided customers with the ability to object many weeks after data collection began.

X did not immediately respond to a request for comment that day. The X Global Government Affairs account announced last week that the company will continue to cooperate with the DPC on AI issues.

In June, Facebook parent company Meta said it would temporarily postpone the launch of its AI assistant in Europe at the suggestion of the Irish DPC.

NOYB has also raised objections to the use of personal data for software training in multiple countries.
