This scripts adds a block filter by country when searching or browsing novels. What it does is hiding results whose countries you choose to block. It does not affect the listing in any other way.
It also supports rec-list. It's a pretty straight forwards script, check screenshot to see what is added to the page.
This script is compiled from Typescript, so it's bad to read directly. Please go here for the source code.
Please raise an issue in the github issue page if something is not working.
