Substack Blocker troch Hausgeist

This addon blocks visits to publications hosted on Substack. It not only works for obvious substacks with an address of "xyz.​substack.​com" but also publications behind a custom domain name.

The addon detects substack hosting based on a header when visiting a site. Hence it requires "Access your data for all websites" permissions. The addon does not otherwise process or transmit any data, and does not use any sort of analytics or telemetry.

Why all this? Because Substack is a nazi bar, and I don't want to end up in nazi bars, not even by accident.

Im accepting bug reports and non-AI code contributions at codeberg.org/hausgeist/substack-blocker.
