Welsh women have described feeling violated after finding their photographs being shared and requested by men on internet chatrooms. The threads on web forum Reddit are home to scores of men who ask for and trade explicit pictures of unsuspecting women.
Some of the threads are public, and are often only live for a few days before they are taken down. Others are set to be private and only people approved by moderators can view the photographs and take part.
In the chatrooms, people post photographs of women and ask if anyone knows who they are or have other photographs of them. There are offers to trade photographs and explicit photographs are posted.
