Louisiana's state attorney general has sued Roblox Corporation for perpetuating "an online environment in which child predators thrive."

Roblox Corp. shares fell as much as 11% Friday after the company, which operates an online video-game service popular with children, was accused in two lawsuits of failing to sufficiently protect youngsters on its platform.

Louisiana's attorney general is suing Roblox, alleging it has and continues to "facilitate the distribution of child sexual abuse material and the sexual exploitation of Louisiana’s children."
