📃 How to Acquire the Blocklist

• The first option is to generate your own list using the blocklist generator - recommended for users who want to tailor the list to their specific needs and preferences.
• The second option is to use the default list - ideal for those who prefer a quick and straightforward solution without any configuration.

Important

I do not allow commercial use of my lists. Lists that I did not create are distributed in accordance with 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.

Important

Please do not download the lists too frequently (e.g., every few hours). It is recommended to download them no more than once per day. Frequent downloads are unnecessary, as the lists are updated only twice during the night (Polish time). More information can be found here.
