X is facing an investigation by the Irish media regulator over concerns about the handling of harmful and illegal material, according to regulatory statements.

Ireland’s media regulator, Coimisiún na Meán, is examining X’s content moderation practices amid concerns that the platform has failed to remove illegal material reported by users. The investigation, launched under the EU’s Digital Services Act, will also assess whether X properly informs users of their rights to appeal moderation decisions.

The social media platform, owned by Elon Musk, has drawn scrutiny for its algorithmic promotion of certain political viewpoints.

The investigation adds to mounting regulatory pressure on X across multiple jurisdictions as authorities examine social media platforms’ content policies and their impact on political discourse.
