This repository is a curated collection of domain blocklists for various categories (ads, malware, porn, etc.) with automated build and maintenance pipelines. It ingests raw domain lists from community submissions and upstream sources, normalizes them, and outputs them in multiple formats (plain text, AdGuard, dnsmasq, etc.) suitable for use in DNS-level content filtering. The project includes a Python package for list processing (normalization, validation, merging), scripts for triaging issues, and GitHub Actions workflows for continuous integration and release management. It serves as a central resource for users of Pi-hole, AdGuard Home, and similar DNS filtering tools. The codebase is well-structured with tests and CI, though the core logic is tightly coupled to the project's configuration and domain-specific rules.
