Can AI image generators be policed to prevent explicit deepfakes of children?

As one of the largest training' datasets has been found to contain child sexual abuse material, can bans on creating such imagery be feasible?

Child abusers are creating AI-generated deepfakes" of their targets in order to blackmail them into filming their own abuse, beginning a cycle of sextortion that can last for years.

Creating simulated child abuse imagery is illegal in the UK, and Labour and the Conservatives have aligned on the desire to ban all explicit AI-generated images of real people.
