In the context of the public-private partnership between TikTok, law enforcement agencies, and Europol, the partners conducted a Referral Action Day to target suspected terrorist and violent extremist content online. The public-private partnership aims to address terrorists' abuse of the Internet, prevent online radicalisation, and safeguard fundamental rights.

The Referral Action Day, which took place on 28 September 2023, was put in motion by Spain and the EU Internet Referral Unit of Europol's European Counter Terrorism Centre (EU IRU) in cooperation with law enforcement authorities from 10 countries. Investigators were able to assess and flag to TikTok 2145 pieces of content for voluntary review against TikTok's terms of service. Referred content included videos and memes linked to jihadism and violent right-wing extremism and terrorism.
