Over 500 schools and universities in South Korea are dealing with a deepfake porn crisis. Explicit images and videos of classmates and teachers are being shared. The perpetrators are often students themselves. In fact, 80 per cent of those arrested for creating and distributing deepfakes are teenagers.

Hyojung Kim from the BBC’s Korean Service explains what’s happening and what’s being done to stop it.

Plus, presenter and campaigner Jess Davies gives us tips on what to do if you have been deepfaked.
