Child safety groups urged pornography websites to introduce age verification tools as quickly as possible to better protect children from harmful content and to bring them in line with the British Board of Film Classification ratings. Video works that are given ratings of between 12, 15, 18, or R18 certificates are legally restricted, and it is against the law for anybody underage to obtain such material. They argue that many porn sites feature depictions of practices that meet the definition of criminal standards for sexual violence.
