Fed up with crypto spam bots and scams in YouTube comments? So was I.
After seeing countless spam and scam comments (and hearing real stories of people losing life savings to comment scams), I decided to build something to help.
SpamBlocker for Youtube - is a personal project, built because I wanted to make YouTube safer for myself and others.
1. Instantly hides spam and scam comments on any YouTube video
2. Blocks comments based on a **predefined pattern blocklist** (e.g. common crypto spam patterns)
3. Lets you **add your own blocklist keywords** for custom filtering—your additions also help build a community-powered suggested blocklist for everyone
4. One-click “Report Spam” button to crowdsource detection and help others
5. See how many spam comments were blocked on each page and overall
6. Community-powered: The more people use and report, the better it will get
How it works:
1. Open any YouTube video—spam comments vanish automatically
2. Add your own keywords to the blocklist or use smart suggestions
3. Click “Report Spam” to flag new patterns and help others
4. Manage everything from the extension popup and track your impact
Key Features:
🛡️ Automatic hiding using a keyword and pattern blocklist (e.g. crypto spam)
👥 Community-powered detection (secure & anonymous)
🚩 One-click spam reporting
🔑 Add your own blocklist keywords—help shape the suggested community blocklist for everyone
📊 See your impact: spam removed per page & in total
Privacy:
Your privacy is respected: All filtering is local except for reporting, which is anonymous and stored securely.
No personal info is ever collected or shared.
Note:
Right now, this extension is focused on fighting crypto spam and scams (where the problem is worst), but as more people use and report spam, we can expand it to remove all types of spam comments from across YouTube—no matter the topic.
Coming soon:
With more users and reports, I hope to build a machine learning powered spam detector for future versions. I already have a base model in development, and your participation will help make YouTube safer for everyone!
**Let’s make YouTube a safer place for everyone!**
