Worked on maintaining and updating content filtering rules for the uBlockOrigin/uAssets and AdguardTeam/AdguardFilters repositories, focusing on adapting to external domain changes. Addressed domain migration from motherless.com to motherless.xxx by updating ad-block and allowlist filters using Adblock Filter Syntax and configuration management skills. Ensured that content blocking and user protection remained effective throughout the transition, verifying compatibility and preventing regressions in filtering logic. Collaborated with other contributors to maintain code hygiene and clear traceability, using plaintext for filter definitions. The work emphasized filter management and web development, prioritizing stability and user safety during ongoing domain migrations and updates.
