On 3 April, essential child protection systems used by technology companies to detect and remove online child sexual abuse material will become illegal to operate in the EU unless the European Parliament votes to extend the current legal framework. A temporary law allowing voluntary detection is expiring, and political deadlock has stalled a permanent solution. This will create a dangerous legal vacuum that perpetrators are aware of and poised to exploit. Proven tools like hash‑matching - which do not compromise privacy - would be forced offline, enabling millions of known abusive images to resurface. Research shows these systems deter offenders and make access harder; disabling them will reverse this progress. MEPs have one final chance to act by voting for an amendment that preserves protections for children across Europe.
