For #2 I assume a PR to remove the site could be sent and merged

For #1 it seems to mostly be a list of SEO gaming sites that I've personally found to be supremely irritating and deserve to be in the list. They basically just mirror stack overflow and GitHub issues and provide obscured links back to the original source to make sure people stay on their site. You can peruse the list in the code yourself. It's just a text file

I don't like low effort clones either. My only concern is the susceptibility of this project to being weaponized by dishonest actors. Some of us have been on the receiving end of false-flag spamming campaigns by competitors and have been penalized unfairly for it. If these filter lists take off, and I hope they do, they must have a well-documented process for accepting patches and another for handling malicious actors.
