  • Mission is to keep users safe at Roblox and right now the main focus is abuse reporting

  • This pod focuses on building the infrastructure to monitor users behavior and move it toward more civil engagement (ex: rather than punishing people, this team focuses on rewarding you for being civil.)

  • Essentially focused on building data driven features for Roblox’s main user experience. These features are primarily aimed at monitoring user activity, building a reputation system to reward users who behave well on the platform, and building features to allow users to report bad or questionable content for moderators to analyze.

  • 30-40M abuse reports per month
