You can block a subscriber from your channel in YouTube Studio

To block a subscriber, go to YouTube Studio, find the Community tab, and select the subscriber you want to block. Click the three-dot menu next to their name and choose "Block user." That person will no longer be able to see your channel, comment on your videos, or send you messages. They won't receive a notification that you blocked them.

Blocking is different from deleting a comment. When you delete a comment, that person can still see your channel and post again. When you block someone, they're locked out entirely. You can unblock them later if you change your mind.

Key Takeaways

  • Open YouTube Studio, go to Community, and find the subscriber's name to block them in one action.
  • A blocked subscriber cannot view your channel, comment, or message you, but they won't know they're blocked.
  • You can see a list of all blocked users in YouTube Studio and unblock anyone at any time.
  • Blocking a subscriber is permanent until you manually unblock them — they don't automatically regain access after a set time.

How to block someone from the Community tab

Open YouTube Studio on a computer or phone. Click the Community tab on the left side menu. Scroll through your subscribers or use the search box to find the person you want to block. Once you find them, click the three-dot menu icon next to their name.

A dropdown menu will appear with several options. Select "Block user" from that menu. YouTube will ask you to confirm — click "Block" again to finish. The person is now blocked and cannot interact with your channel. The entire process takes less than a minute.

How to block someone from their profile or comments

If someone has commented on your video or you've visited their profile, you can block them directly from there. Click on their username or profile picture to open their channel. Look for the three-dot menu icon near the top of their profile page and select "Block user."

You can also block someone while reviewing comments on your videos. Find their comment, click the three-dot menu next to it, and select "Block user." This removes their comment and prevents them from posting again. This method is faster if you're already moderating comments and spot someone you want to block.

What happens when you block someone

A blocked person cannot search for your channel, view your videos, or see any of your content. They cannot comment on your videos, like them, or subscribe to you. If they were already subscribed, they are automatically unsubscribed. They also cannot send you direct messages through YouTube.

The blocked person will not receive a notification saying you blocked them. However, if they try to visit your channel, they will see a message saying the channel doesn't exist or they don't have permission to view it. This can tip them off that they've been blocked, though YouTube doesn't explicitly tell them so.

How to see and manage your blocked users list

Go to YouTube Studio and click Settings in the left menu. Select "Community" or "Moderation" depending on your account type. Look for "Blocked users" — this shows everyone you've blocked. You can scroll through the list to see who is currently blocked on your channel.

To unblock someone, find their name in the list and click the X or "Unblock" button next to it. They will immediately regain access to your channel. You can block and unblock the same person as many times as you need to. There's no limit to how many people you can block.

Blocking vs. other moderation tools

YouTube offers several ways to control who interacts with your channel. Blocking is the strongest option — it removes someone entirely. Deleting comments only removes that single post; the person can still watch and comment again. Disabling comments on a video stops all comments on that video but doesn't affect the person's access to your channel.

You can also use YouTube's filter settings to automatically hold comments for review before they appear. This lets you catch spam or unwanted comments before your audience sees them. For repeated problems with specific people, blocking is usually the right choice because it prevents all future interaction.

Frequently Asked Questions

Can someone tell if I blocked them on YouTube?

YouTube doesn't send a notification, but they may figure it out if they try to visit your channel and see an error message. They won't know for certain unless they ask you directly or try to interact with your content and find they can't.

What if I block someone by mistake?

Go to YouTube Studio, open Settings, find "Blocked users," and click the unblock button next to their name. They will immediately have access to your channel again. There's no waiting period or confirmation needed to unblock.

Does blocking someone delete their old comments?

No. Comments they posted before you blocked them will still be visible on your videos. If you want to remove those comments, you need to delete them separately. Blocking only prevents them from posting new comments going forward.

Can I block someone who isn't subscribed to my channel?

Yes. You can block anyone — subscribers, non-subscribers, or people who have never visited your channel. You can block them from their profile, from a comment they left, or by searching for them in YouTube Studio's Community section.

Will blocking someone affect my subscriber count?

If they were subscribed when you blocked them, they will be unsubscribed automatically. Your subscriber count will drop by one. If they were not subscribed, your count stays the same.
