In June 2025, Emil Schaetzle expanded ad-blocking coverage for Joyn.ch within the uBlockOrigin/uAssets repository, focusing on filter list management and domain-specific blocking. Emil delivered a feature that incorporated Joyn.ch into the filter set and applied a no-fetch-if rule to block ad-related fetches, thereby improving privacy and reducing unnecessary network requests. The work was implemented using text-based filter syntax and demonstrated a clear understanding of ad blocking and maintainable filter list extension. By tracking the change in a single commit, Emil ensured traceability and reviewability, contributing a focused, well-scoped enhancement to the widely-used uAssets ad-blocking ecosystem.
