wtf is domain-list-community?

This project is a community-maintained collection of domain name lists. The lists are used as routing rules inside V2Ray and its related tools, which are network proxy applications. The idea is simple: group domains by category (for example, Chinese sites, advertising networks, media streaming services, developer tools), then let a proxy tool use those groups to decide how to handle traffic to each domain: block it, send it directly, or route it through a proxy. The output of this project is a compiled file called dlc.dat, which proxy tools can load. Pre-built versions are available as GitHub release downloads, so most users never need to run any code themselves. The file is regenerated automatically when the community updates the domain lists. For those who want to build the file themselves or create custom variants, the project includes a Go program that reads the plain-text data files in the repository and compiles them into the binary format. Each data file holds a list of domains for one category. Rules can match by subdomain, full domain, keyword inside the domain name, or regular expression. Domains can also carry tags (called attributes) to mark subgroups, such as ad-serving domains within an otherwise legitimate service, which allows very fine-grained filtering. The data directory is the core of the project. Files there are named after what they contain: google, netflix, cn, category-ads-all, and so on. Anyone can submit a pull request to add or correct domains, and an automated check runs on every pull request to catch errors before merging. The project explicitly does not take a position on what should be blocked or proxied, it just provides organized lists that users configure as they choose. This is primarily useful to people running V2Ray or compatible proxy tools who want up-to-date, community-verified routing rules without maintaining their own domain lists by hand.
