Roblox is adding new restrictions to younger kids’ accounts and revamping its parental control features as part of a push to beef up the safety features on its platform.

Roblox is starting to roll out some recently-announced child safety features, and the updates include some new limitations for how users under 13 can communicate on the platform. Beginning Monday, users younger than 13 won’t be able to DM players outside of games or experiences on Roblox.
