A simple blocklist for your X timeline. Check a country in the popup and its posts vanish from your For You feed, Following feed, search, and reply threads. Uncheck it and they come right back — everything else stays untouched. No sign-up, no tracking, no external servers; your settings stay in your browser. Detection runs locally: known accounts, country/city keywords, post language, and the author's public profile location. Open source (MIT).
