## What it is
A set of uBlock Origin filter lists that hide copycat and SEO-spam websites from search results on Google, DuckDuckGo, and other engines. It focuses on developer sites like StackOverflow and GitHub, and also covers Wikipedia and general spam.

## Use cases
- hide StackOverflow clone sites from Google search results
- remove SEO spam from DuckDuckGo results

## When to choose

- you are tired of copycat dev sites outranking originals
- you want a lightweight, subscribeable filter list

## When to avoid
