3. Trust & Safety Unit Economics & Architecture

A. Safety CapEx / OpEx per Active User

Roblox: Allocates $1.80 – $2.50 per DAU annually, relying heavily on low-cost BPO moderators in developing nations with 3–10 second review quotas per ticket.
Epic Games (Fortnite): Spends $12.00 – $18.00 per DAU annually following its 2022 FTC consent decree, utilizing patented rolling encrypted voice buffers and in-house safety teams.
Minecraft (Microsoft): Backed by Microsoft's enterprise-wide $1B+ digital safety and Azure Content Safety AI stack.

B. Voice Chat Safety Mechanisms

Epic Games Rolling Audio Buffer: Client-side 5-minute rolling encrypted audio cache. Audio is recorded cyclically and overwritten. When a report is filed, the encrypted buffer is decrypted and uploaded with cryptographic timestamps.
Roblox Spatial Voice: Relies on third-party identity photo verification (Persona/Veriff) with no client-side audio telemetry buffers, making post-session verbal grooming nearly impossible to substantiate.
