## What it is
A repository of AdGuard's content-blocking filter lists — text-based rule sets used by AdGuard apps and other ad blockers like uBlock Origin to block ads, popups, and trackers. It is actively maintained with regional and purpose-specific filters, and accepts community reports of missed ads and false positives.

## Use cases
- subscribe to a maintained ad-blocking filter list in uBlock Origin
- block trackers and spyware with a tracking protection filter
- find region-specific ad filters like German or Russian lists
- report false positives or missed ads to a filter maintainer
- remove social media widgets and cookie notices from web pages
- build a custom ad-blocking setup with curated filter lists

## When to choose
- you need actively updated, community-supported ad and tracker filter lists
- you use AdGuard products or uBlock Origin and want high-quality filters
- you need regional or purpose-specific filtering (social media, tracking protection)
- you want to contribute filter rule fixes via GitHub issues

## When to avoid
- you need an ad-blocking application itself rather than filter rule data
- you need DNS-level or network-wide blocking rules in a different format
- you want a one-time static list with no ongoing updates
