Roblox has announced a number of built-in features that will limit what users younger than 13 can do following increased scrutiny.

Video game maker Roblox said on Monday that it is implementing new safety measures for users under 13, including permanently removing the ability to message others outside games on its platform.

A lawsuit has been filed against Roblox, claiming a 13-year-old girl in St. Louis was exploited by a pedophile.

Police say a 37-year-old man groomed an Iowa teen he met on game platform Roblox, then drove her Tennessee, his home state, to sexually assault her.
