CB Quick Silence + Image Hash Guard (Supabase Sync)

A Tampermonkey userscript that adds a red Silence button (if you’re mod/broadcaster), auto-silences by username/trigger word, and now also detects repeat image spam using a fast dHash (64-bit) matcher. Optional soft audio cue on detection. Polled data comes from Supabase (shared by default, or use your own).

📌 What this script does

Silence button next to each username (mods/broadcasters only).
Auto-silences messages from usernames on a Supabase list.
Auto-highlights suspicious messages (when you’re not privileged).
Trigger-word scanning (from Supabase).
Image Hash Guard: computes a 64-bit dHash on images/GIFs/video posters in chat messages, compares to your uploaded reference hashes, and:
- beeps softly on match (optional),
- auto-silences (if privileged & enabled),
- or highlights (if not privileged).
Floating settings panel (“QS ⚙️” bottom-left) for toggles, thresholds, audio tune, and reference management.
Periodic Supabase sync (configurable). Uses GM_xmlhttpRequest → CSP-safe.
DB overlay to view active auto_silence_users with notes/reasons.

⚙️ How it works

On room enter, script checks if you’re mod/broadcaster.
Pulls usernames and trigger words from Supabase; re-syncs on a timer.
Scans each chat message:
- If privileged and matches → POST to /roomsilence/{user}/{room}/
  (never includes /b/; CSRF handled).
- If not privileged and matches → highlight only.
Image Hash Guard:
- Extracts all image/video URLs in the message.
- Computes dHash (8×8, 64-bit) and compares with your stored references.
- If Hamming distance ≤ threshold → match → optional beep, auto-silence/highlight.

✨ Features

Text/User rules: usernames + trigger words from Supabase.
Image rules: local reference hash list (dHash), threshold-based matching.
Soft audio cue: subtle sine beep with low-pass filter; tunable volume/duration/frequency; once-per-message option.
Cooldown per image URL to avoid re-spamming detections.
No note prompt on manual silence (fast action).
SPA-safe: watches DOM changes, handles room navigation.
CSP-safe: uses GM_xmlhttpRequest with @connect to Supabase.

🖥️ Requirements

A userscript manager:
- Tampermonkey (recommended)
- Violentmonkey (ensure @connect permissions are allowed)
Runs on https://*.chaturbate.com/* (and optional testbed as configured).

🔧 Installation

Install Tampermonkey.
Install the script from SleazyFork (or paste the code into a new userscript).
Open any Chaturbate room.
Look for the “QS ⚙️” button (bottom-left) and the Silence buttons in chat.

🧩 The Settings Panel (QS ⚙️)

Click QS ⚙️ to open the floating panel.

Core

Auto Silence: on/off
Highlight Matches: on/off
Show Silence Buttons: on/off (mods only)
Poll interval (sec): set Supabase sync period
Sync now: force refresh from Supabase
Show DB list: open the overlay that lists active auto_silence_users

Image Hash Guard

Enable image-hash detection: master toggle
Threshold (0..64): Hamming distance; lower = stricter
Detect in mod/broadcaster messages: include/exclude staff posts
Add reference images…: upload one or more images to build your reference hash set
Clear references / Delete single entries

References are local to your browser (stored with Tampermonkey’s storage). Nothing is uploaded anywhere.

Audio (soft)

Beep on match: toggle
Volume: 0.0–1.0 (gentle default)
Tone (Hz): pitch of the sine wave
Duration (s): how long the beep lasts
Lowpass (Hz): smooth the sound
Once per message: avoid multiple beeps for many images
Test: play a sample beep

🌍 Supabase (Global Defaults)

By default, the script points to a shared Supabase project that provides:

auto_silence_users — who to silence
trigger_words — what to flag

You benefit from live updates without touching the code.

🛠️ Use Your Own Supabase (Optional)

Prefer full control? Set your own:

SUPABASE_URL
SUPABASE_ANON_KEY (or service key if you keep the script private)

Tables expected:

auto_silence_users with (at least)
username (text), is_active (bool), and timestamps.
trigger_words with (at least)
word (text), is_active (bool), and timestamps.

The script queries with select=* and filters is_active=true. Adjust your schema accordingly.

🔒 Privacy

The script does not exfiltrate your data anywhere.
All reference image hashes are stored locally in Tampermonkey storage.
Network requests go only to:
- Chaturbate endpoints for moderation actions
- Supabase for list sync

🧯 Troubleshooting

No Silence buttons? You’re likely not recognized as mod/broadcaster. The script auto-detects privileges via the room API.
403 on silence? CSRF cookie missing or you’re not a mod. Reload the page or switch to a room where you have privileges.
No image matches? Ensure Image Hash Guard is enabled, references exist, and threshold isn’t too strict. Try 8–12 as a starting range.
Too many beeps? Enable Once per message and/or reduce volume.
High CPU? Keep your reference set reasonable. The dHash compare is fast, but thousands of refs are pointless.
