📦 How to Acquire the Blocklist

  • The first option is to generate your own list, recommended for users who want to customize the list based on their specific needs and preferences.
  • The second option is to use the default list provided, ideal for those who prefer a quick, straightforward solution without customization.

Important

I do not allow commercial use of my lists. Lists I did not create are shared under the licensing terms set by their original authors. If you wish to use the Sefinek Blocklist Collection for commercial purposes, please contact me via email. Do not download the lists every hour either. Click here to learn more.

❌ How to Report a False Positive? (more info)

False positives can be reported by creating a new Issue, submitting a new PR (just remember to follow the required syntax, see whitelists/main.txt), on our Discord server, or by contacting me via email.
Within 96 hours, I will add the domain to the whitelist. Shortly after, the false positive will be automatically removed from the blocklist by GitHub Actions.
