Comment Vaccinator – YouTube Comment Filter από ShockWave

Clean up YouTube comments by automatically filtering repetitive date comments, keyword spam, low-effort posts, and unwanted phrases.

Comment Vaccinator helps you focus on meaningful discussions by removing comments such as "Anyone here in 2026?", "First!", "Subscribe", repetitive keywords, and other low-value clutter in real time.

Customize filtering with date detection, word-count rules, keyword blacklists, emoji-aware counting, and live comment statistics.

Detects and filters date-based comments in both English and Hindi (Devanagari) formats.
This extension surgically removes date-like comments, word-count spam, and keyword clutter from YouTube — automatically, in real time.

🗓️ Date Filter
Automatically hides comments containing date patterns:
“Anyone here in 2026?”, “Watching this today!”, “Jan 12, 2025”
“12/04/24”, “Monday gang”, “11th of September”
Supports English + Hindi/Devanagari date formats
Toggle ON/OFF anytime — comments reappear instantly

📏 Word Count Filter
Two modes to control comment length:
Max mode — Hide comments with FEWER words than your threshold (zaps short spam like “Nice” or “First!”)
Min mode — Hide comments with MORE words than your threshold (zaps long rambles)
Adjustable range: 3–50 words
Optional Strict Emoji Cleanup removes emojis before counting for accurate results

🔑 Keyword Blacklist
Block comments containing specific words:
Comma-separated list (e.g., ad, sponsor, first, subscribe)
Works independently of date filter
Case-insensitive matching

🛡️ Keyword Whitelist
Protect comments containing specific words:
Comma-separated list — matching comments always stay visible
Overrides all other filters — whitelist always wins
Green border, green-tinted background when enabled

🔧 Custom Patterns
10 preset regex patterns for common spam + add your own:
Presets ship inactive until you enable the toggle
Add/edit/delete custom patterns via regex editor
Reset to defaults restores the 10 OOTB presets (your custom patterns are kept)
