YouTube's blocking tools work in three layers: hiding someone's channel, preventing them from contacting you, and reporting serious threats

Blocking on YouTube does not work the way it does on other platforms. There is no single "block" button that stops someone from seeing your videos or commenting on them. Instead, you get separate controls for hiding a channel from your recommendations, preventing direct messages, and reporting abuse. Understanding which tool does what matters, because blocking someone's channel does not stop them from watching your public videos — it only hides their uploads from your feed.

The most common reason to block is to stop someone from commenting on your videos or sending you messages. That is the blocking action YouTube actually enforces. If you want to prevent someone from seeing your content entirely, that requires making your videos private or unlisted instead.

Key Takeaways

  • Blocking a channel hides that person's uploads from your recommendations and prevents them from messaging you, but does not stop them from watching or commenting on your public videos.
  • You can block someone from your subscriptions list, from their channel page, or from a comment they left on your video — each route takes two clicks.
  • If someone is harassing you across multiple accounts, report the behavior to YouTube rather than blocking each account separately, because YouTube can investigate patterns.
  • Making a video private or unlisted is the only way to stop someone from seeing it; blocking alone does not hide your content from them.

How to block someone from your subscriptions or recommendations

If you subscribe to someone and want to stop seeing their uploads in your feed, go to your Subscriptions page. Find the channel name, click the three-dot menu next to it, and select "Block user." That person's videos will no longer appear in your recommendations or your subscription feed. They can still watch your public videos and comment on them, but you will not see their new uploads.

You can also block someone directly from their channel page. Visit their channel, click the three-dot menu icon (usually in the top right), and select "Block user." This does the same thing as blocking from your subscriptions — it removes them from your feed and prevents them from messaging you. Both routes take about two clicks and take effect when ready.

How to block someone who commented on your video

If someone leaves a comment you do not want to see again, hover over the comment and click the three-dot menu. Select "Block user." This prevents that person from commenting on any of your videos going forward and hides their previous comments from your view. Other viewers will still see their old comments unless you delete them separately.

Blocking a commenter is different from deleting a comment. When you delete a comment, everyone sees it is gone. When you block the person, only you see their comments as hidden — other viewers still see them. If a comment violates YouTube's rules, report it instead of just blocking, so YouTube can review it and potentially remove it from the platform.

What blocking does and does not prevent

Blocking prevents someone from messaging you through YouTube's direct message system. It also hides their channel from your recommendations and removes their comments from your view. But blocking does not stop them from watching your public videos, subscribing to your channel, or leaving comments that you will see if you visit your comments section directly.

If you want to actually prevent someone from seeing your content, you need to change the video's privacy setting. Go to the video, click "Details," and change the privacy from "Public" to "Private" (only you and people you invite can see it) or "Unlisted" (anyone with the link can watch, but it does not appear in searches or recommendations). This is the only way to hide your videos from a specific person.

When to report instead of block

If someone is harassing you, threatening you, or posting content that breaks YouTube's rules, report them rather than just blocking. Go to their channel or their comment, click the three-dot menu, and select "Report user" or "Report comment." YouTube's safety team reviews reports and can remove content, suspend accounts, or escalate to law enforcement if the threat is serious.

Blocking is useful when you straightforward do not want to see someone's content. Reporting is the right move when someone is breaking YouTube's Community Guidelines — which cover harassment, hate speech, threats, and spam. If the same person keeps harassing you from different accounts, report each account and mention in the report that it is a pattern. YouTube can see account connections and may take broader action than blocking a single account would.

How to unblock someone

If you change your mind, you can unblock someone. Go to your account settings, click "Privacy" in the left menu, and scroll down to "Blocked users." You will see a list of everyone you have blocked. Click the X next to their name to unblock them. They will be able to message you again and their videos will reappear in your recommendations.

Unblocking takes effect when ready. The person will not be notified that you unblocked them, just as they were not notified when you blocked them. You can block and unblock the same person as many times as you need to.

Frequently Asked Questions

Can someone tell if I blocked them?

No. When you block someone, they cannot see your channel or send you messages, but YouTube does not notify them that they are blocked. They may figure it out if they try to message you and the message fails, but YouTube does not send a "you have been blocked" notification.

If I block someone, can they still see my old comments on other channels?

Yes. Blocking only affects your channel and direct messages. Your comments on other channels, your likes, and your public activity remain visible to that person unless you delete them yourself.

What happens if I block someone and then they create a new account?

The block only applies to the specific account you blocked. If they create a new account, that account is not automatically blocked. If the same person keeps harassing you from multiple accounts, report the pattern to YouTube instead of blocking each account individually.

Does blocking stop someone from seeing videos I made public?

No. Blocking only affects your channel page, recommendations, and messages. If your video is public, anyone can find it through search or a direct link, even if you blocked them. To prevent someone from seeing a specific video, change its privacy to Private or Unlisted.
