To release a new version:
version in package.json.npm run build (regenerates root youtube-bot-comments-filter.user.js / .meta.js).CHANGELOG.md.main (or create a GitHub Release).@SAWS.PW__TyT_Ha_CauT_05)| Site | URL pattern |

Works on watch pages, Shorts with comments, and any YouTube view that renders the standard comments section (ytd-comment-view-model / ytd-comment-renderer). |
| Mode | Behavior |
|---|---|
| Hide (default) | Comment body is replaced by a short notice; layout stays stable |
| Blur | Bot comments appear blurred, grayscale, and semi-transparent; full content shows on hover |
| Open your avatar menu → Bot filter → choose a mode. The subtitle under the menu entry shows the current mode. |

Run BotDetector rules → sum weights
│
├── score < threshold ──► leave comment unchanged
│
└── score ≥ threshold ──► apply hide notice or blur
Detection is based on the commenter's display name, not comment text. Each rule has a name, weight, and test(name) function. The total score is the sum of matched rule weights. If the total is ≥ 4 (default threshold), the comment is flagged as a bot.
Built-in signals include:
| Signal | Weight | Example |
|---|---|---|
| Domain-like prefix with spam TLD | 3 | @SAWS.PW__..., @TLES.TOP-... |
| Separator right after TLD | 2 | .PW__, .TOP- |
| Transliterated spam keywords | 3 | tyt_ha, na_caut, smotri, 4ki_na |
| Many underscores | 1 | three or more _ in the name |
| Leetspeak digit in word | 1 | Sy4ki, CauT0 |
| ALLCAPS prefix with dot | 1 | @SAWS.PW |
| Exact match list | 100 | SAWS.PW, TLES.TOP |
Spam TLDs checked: PW, TOP, XYZ, ONLINE, SITE, CLUB, WIN, CC, ICU, VIP, and others commonly abused in bot nicknames. |
||
To extend detection, edit EXACT_MATCHES / SPAM_TLDS in src/constants.js or push new objects into RULES in src/detection/bot-detector.js. |
YouTube loads comments asynchronously (infinite scroll, replies, navigation without full reload). A MutationObserver on document.documentElement schedules debounced passes via requestAnimationFrame. A 2-second safety interval catches any missed mutations.

Requires Node.js 20+ (npm).
npm install
npm run dev # Vite serve — open/install the generated "dev:" userscript
npm run build # Production → dist/ + copy to repo root
npm run ci # Same checks as GitHub Actions (build + verify artifacts)
Edit files under src/ (entry: src/main.js). Userscript metadata (@match, localized names, …) lives in vite.config.js. Version is package.json → header @version and in-script SCRIPT_VERSION.
After changes that should ship, run npm run build and commit the regenerated root .user.js / .meta.js. Pull requests run CI, which fails if those files are out of date.
npm run dev: vite-plugin-monkey serves an installable userscript (name prefixed with dev:). Install it once in Tampermonkey, Violentmonkey, or ScriptCat; HMR applies while the server runs.npm run build, you can also install the root youtube-bot-comments-filter.user.js (Violentmonkey Track local file still works on that artifact).@updateURL / @downloadURL values.| Constant | Default | Location | Description |
