A sexual violence victims advocate says a court ruling which gives a woman at the centre of a revenge porn case support from ACC, demonstrates the delays in legislation to keep up with technology.

The woman fought to receive ACC cover for years, after suffering PTSD when her former partner shared a sex video on one of the world's largest porn sites.

ACC declined her claim because it did not recognise what happened as a crime, but a district court judge has disagreed.

ACC will pay her out, but says it's still trying to understand the implications of the decision.
