Roblox has been slammed as a "hunting ground for child-sex predators" in a new lawsuit against the online gaming giant that alleges it caused the sexual exploitation of a 9-year-old boy.

Roblox presents itself to parents as a safe space for kids. Behind the scenes, it's waging a technological shadow war against condo games: digital sex parties where kids are flirting with danger.

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

Roblox is no longer allowing users under the age of 13 to message others outside of games and experiences on the platform.
