When Kate’s 13-year-old son took up Minecraft and Fortnite, she did not worry.
The video games were hardly Grand Theft Auto — banned in their home because it was too violent — and he played in a room where she could keep an eye on him.
But about six weeks later, Kate saw something appalling pop up on the screen: a video of bestiality involving a young boy. Horrified, she scrolled through her son’s account on Discord, a platform where gamers can chat while playing. The conversations were filled with graphic language and imagery of sexual acts posted by others, she said.
