It described how anonymous accounts made tracking predators difficult on the site and moderation teams were struggling with its increasing popularity.
The new measures allow parents to monitor their children’s activities and screen time much more closely from their own devices.
Under-13 users will no longer have access to direct messaging outside games, and will be limited to public broadcast messages within experiences by default, the company said.
“Safety is and always has been foundational to everything we do at Roblox,” said Matt Kaufman, chief safety officer.
The platform is also abandoning age-based content ratings in favour of content-type labels. Users under the age of 9 will be restricted to “minimal” or “mild” content unless parents approve access to “moderate” content.
“These updates should provide parents greater clarity to make informed decisions about what is appropriate for their child,” the company said.
The US-based Family Online Safety Institute (FOSI) endorsed the changes. “Roblox is taking significant steps toward building a safer digital environment,” said FOSI CEO Stephen Balkam.
Full implementation of the new rules is expected by 2025, the company said.
