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

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.
