In February 2025, Boris Krisanov enhanced the lichess-org/lila repository by refining how user profile study counts are calculated to better respect privacy. He implemented a viewer-aware filter in Scala, ensuring that only studies which are public or accessible to the viewer are included in the profile count, while private studies are excluded. This backend development work introduced the hasMemberOrIsPublic filter, aligning visible profile metrics with actual user permissions. The focused change improved the accuracy of public-facing data and addressed privacy concerns, demonstrating a thoughtful approach to user data handling and access control within a Scala-based backend environment.
