Ultra-Sleek Pure #000000 Dark Mode & Automated NSFW Board Blocker for 4chan / 4channel Transform 4chan into a high-contrast, OLED-friendly true black experience while automatically blocking and redirecting away from adult / NSFW boards.
Click the button below to install directly into your userscript manager (Tampermonkey, ScriptCat, Violentmonkey, or Greasemonkey):
- 🛑 Automatic NSFW Board Redirect: Instantly redirects visitors attempting to access NSFW / adult boards (
/b/,/r9k/,/pol/,/gif/,/h/,/hc/,/hm/,/aco/,/soc/, etc.) back to the main homepage before content renders. - 🖤 True #000000 Pitch Black Theme: Replaces default light/dark themes with pure zero-hex black for maximum energy savings on OLED & AMOLED screens.
- 🎨 Consolidated Styling: Restyles headers, footers, buttons, quote links, thread cards, reply boxes, and scrollbars for a clean, unified aesthetic.
- ⚡ Zero Latency (
document-start): Runs at the earliest possible stage to eliminate flash-of-unstyled-content (FOUC). - 🧩 Zero Dependencies: Lightweight, standalone vanilla JavaScript + injected CSS with zero external library bloat.

/b/ • /r9k/ • /pol/ • /bant/ • /soc/ • /s4s/ • /s/ • /hc/ • /hm/ • /h/ • /e/ • /u/ • /d/ • /y/ • /t/ • /hr/ • /gif/ • /aco/
