如何封鎖 YouTube 頻道 (完整的步驟指南)

To block a YouTube channel, go to the channel’s profile, click the three-dot menu, and select “Block user.” This prevents that channel from commenting on your videos. If you want to stop seeing their content in recommendations, choose “Don’t recommend channel” from a video’s menu instead.

Below is a complete guide covering desktop, mobile, blocking comments, hiding channels from your feed, and parental control options.

How to Block a YouTube Channel on Desktop (Prevent Comments)

If you want to stop a channel from interacting with you:

1. Go to YouTube
2. Visit the channel you want to block
3. Click theAbouttab
4. Click theflag icon
5. SelectBlock user
6. Confirm your choice

This prevents that user from commenting on your videos.

Important: Blocking a channel does not remove their past comments automatically.

How to Block a YouTube Channel on Mobile (Android & iPhone)

On the YouTube app:

1. Open the channel’s page
2. Tap the three-dot menu in the top-right corner
3. SelectBlock user
4. Confirm

This works similarly to desktop and stops that account from interacting with your content.

How to Stop Seeing a YouTube Channel in Recommendations

If your goal is to remove a channel from your homepage or suggested feed:

1. Find a video from that channel
2. Tap the three dots next to the video
3. SelectDon’t recommend channel

YouTube’s algorithm will reduce or eliminate content from that creator in your recommendations.

This method does not notify the channel.

How to Block a YouTube Channel from Commenting on Your Videos

Blocking a channel prevents future comments, but you can also:

• Hide specific users from your channel
• Review held comments in YouTube Studio
• Add words to your blocked keywords list

In YouTube Studio:

1. Go to Settings
2. Select Community
3. Add users to hidden users list

This ensures their comments never appear publicly.

How to Block YouTube Channels for Kids

YouTube Kids

1. Tap the three dots on the video
2. SelectBlock this videoorBlock this channel

How to Block YouTube Channels on Smart TVs

On Smart TVs or streaming devices:

1. Open the YouTube app
2. Find a video from the channel
3. Select the three-dot menu
4. ChooseDon’t recommend channel

Some TV apps may not allow full user blocking, but recommendation blocking is available.

What Happens When You Block a YouTube Channel?

When you block a channel:

• They cannot comment on your videos
• They are not notified
• You may still see their public content unless you hide recommendations
• Past comments may remain unless manually deleted

Blocking focuses mainly on interaction control rather than total visibility removal.

Can a Blocked YouTube Channel Still See Your Content?

Yes. Blocking does not make your channel invisible to them.

If you want stronger privacy:

• Set videos to Private
• Set videos to Unlisted
• Restrict comments

Blocking is not the same as making your channel private.

Difference Between Blocking and “Don’t Recommend Channel”

Blocking a user:

• Stops them from commenting
• Applies to interaction control

“Don’t recommend channel”:

• Removes content from your feed
• Affects your personal recommendations

These are separate features and often used together.

How YouTube’s Algorithm Adjusts After Blocking

Because Google owns YouTube, its recommendation system adapts based on user behavior.

When you:

• Click “Don’t recommend channel”
• Stop watching similar content
• Mark videos as “Not interested”

The algorithm gradually reshapes your homepage feed.

Results may not be immediate but typically improve over time.
