How to Block YouTube Channels and Keywords

Block specific YouTube channels and keywords to prevent your child from accessing unwanted content. Blocked content is hidden instantly across all YouTube pages.

How does Blocked Content work?

Blocked Content works opposite to Approved Channels. Instead of approving content, you block specific channels or keywords:

What happens when content is blocked?

On video watch pages:

• A full-screen overlay covers the video
• Your child sees "This content is not available"
• The overlay cannot be bypassed or dismissed

On browse and search pages:

• Blocked video thumbnails are completely hidden
• Children don't see blocked content in recommendations
• Search results exclude blocked channels and keywords

Where to find blocked content

The Blocked content view is accessible directly from your dashboard:

1. Open the Parents' App on your phone
2. Select your child using the child switcher at the top
3. Tap the Blocked card on your dashboard (it shows the total item count, e.g., "81 items")

This opens the "Blocked Content" view with two tabs: Keywords and Channels.

How to block keywords

Step 1: Open the Blocked Content view

1. Tap the Blocked card on your dashboard

2. You'll see two tabs: Keywords and Channels
3. The Keywords tab is selected by default

Step 2: Add a keyword to block

1. In the search bar at the top, type the keyword or phrase you want to block
2. Tap the Block button to add the keyword

The keyword is immediately added to your blocked list and starts blocking matching content.

Step 3: View your blocked keywords

Your blocked keywords appear in a list, each showing:

• Keyword displayed in red text
• × delete icon to remove the keyword

Below the list, you'll find a Suggested keywords section with common keywords other parents block. Tap any suggestion to add it to your blocked list.

Keyword matching examples

If you block the keyword "ronaldo", these videos will be blocked:

• "Ronaldo Best Goals 2024"
• "Cristiano Ronaldo Skills"
• "Ronaldo vs Messi Comparison"

If you block "HIGHLIGHTS", these videos will be blocked:

• "Match Highlights - Liverpool vs Chelsea"
• "NBA Highlights Today"
• "Best Highlights of the Season"

How to remove a blocked keyword

1. Find the keyword in your blocked keywords list
2. Tap the × icon next to the keyword
3. The keyword is immediately removed and videos with that keyword are no longer blocked

   • Channel handle (e.g., @bundesliga)
   • Channel URL

2. Tap the Block button to search

3. Search results appear showing matching channels with their avatar and handle

Your blocked channels appear in a list, each showing:

• Channel avatar (circular, colored)

Common questions

Can I block a channel that's on my Whitelist?

Yes. Blacklist rules take priority. If you block a previously whitelisted channel, it will be blocked immediately.

Are keywords case-sensitive?

No. Keywords are matched regardless of case. "HIGHLIGHTS" and "highlights" work identically.

How quickly do changes take effect?

Instantly. Changes sync to the browser extension in real-time (typically under 500ms).

Can my child see what's blocked?

No. Blocked thumbnails are hidden. Children only see an overlay message when trying to access a blocked video directly via URL.

What happens when I reach my tier limit?

You'll see an upgrade prompt. You can either:

• Remove existing entries to make room for new ones
• Upgrade your plan for higher limits

Can I export or import my blacklist?

This feature is planned for a future update.

Tips for effective blocking

Block channels, not just keywords

If you want to block a specific creator, blocking their channel is more effective than blocking keywords. Keywords might miss some videos or block unrelated content.

Use specific keywords

Avoid overly broad keywords like "video" or "play" which could block legitimate educational content. Be specific: "prank call" is better than just "call".

Review periodically

Check your blacklist monthly. As your child grows, some blocked content may become appropriate.

Combine with Whitelist

For maximum control:

1. Set protection level to Whitelist Only
2. Add trusted channels to Whitelist
3. Use Blacklist to block specific problematic content

This gives you full control over what your child can watch.
