More than 70 women in a small English town have their private, often nude, pictures stolen and shared online by people who live in their community.
The indecent images, including some underage girls, are believed to have been hacked or provided by people they know and uploaded anonymously to a website that features women from around the world.
Members of this online forum specifically request girls in the places where they live and exchange pictures “like Pokémon cards” for free.
The BBC has spoken to a dozen or so victims in a city who have banded together and formed a group to seek justice.
