The internet’s biggest recreation zone for kids is struggling to keep predators off its platform.

Roblox accepts it has a problem: "We know there is an extremely small subset of users who deliberately try to break the rules," a spokesperson told the BBC.

Roblox is a huge sprawling world of games which is sometimes described as a kind of primitive metaverse. It's one of the most popular children's games in the world.

Roblox is introducing major changes to improve safety and content accessibility for younger users. These updates will come into effect between late November 2024 and 2025.

A BBC investigation has found virtual sex parties are taking place in a popular online children’s game.
