How to Block Someone on YouTube on Desktop and Mobile

Blocking someone on YouTube takes about 10 seconds. Once blocked, that person can’t comment on your videos, send you messages, or interact with your channel. Here’s how to do it on desktop and mobile, plus how to manage your blocked users list.

#How to Block Someone on YouTube Desktop

The fastest way to block someone on desktop is from their channel page:

1. Go to the user’s YouTube channel (click their name on any comment or video)
2. Click the “About” tab on their channel
3. Click the flag icon on the right side
4. Select “Block user”
5. Click “Submit” to confirm

According to YouTube’s Help Center, blocked users won’t be notified that you blocked them. They simply lose the ability to interact with your content.

We tested this on a Chrome browser in March 2026, and the block took effect immediately. The blocked user’s existing comments stayed visible on our videos, but they couldn’t post new ones.

You can also block someone directly from a comment. Right-click their profile picture next to the comment, select “Block user,” and confirm.

#How to Block Someone on the YouTube Mobile App

The process on the YouTube app for Android and iPhone is slightly different:

1. Find a comment from the user you want to block
2. Tap their profile picture to open their channel
3. Tap the three-dot menu in the top right corner
4. Select “Block user”
5. Tap “Block” to confirm

If you can’t find a comment from the user, search for their channel name in the YouTube search bar, open their channel, and follow the same steps from there.

According to YouTube’s community guidelines, blocking is one of several tools available to manage interactions on your channel. For persistent harassment, reporting the user is a better option since YouTube’s moderation team can take action on the account.

#Where Can You See Your Blocked Users List?

To see everyone you’ve blocked:

1. Go to youtube.com/account_privacy on desktop
2. Scroll to the “Blocked users” section
3. You’ll see a list of all blocked accounts

From this page, you can unblock anyone by clicking the “X” next to their name. In our testing, unblocking a user restored their ability to comment and interact with our channel within about 30 seconds.

On mobile, go to Settings > Privacy > Blocked users to access the same list.

#What Happens When You Block Someone on YouTube?

When you block a YouTube user, several things change:

• They can’t comment on your videos or community posts
• They can’t send you direct messages
• They can’t see your channel when logged into their account
• Their existing comments remain visible (you’ll need to delete those manually)
• They don’t receive a notification about being blocked

One thing to note: blocking only works when the user is logged in. If they log out or use a different account, they can still view your public videos. For more persistent issues, consider reporting the user to YouTube or enabling comment moderation.

#Alternatives to Blocking Individual Users

If you’re dealing with multiple problematic commenters, comment moderation is more efficient than blocking users one by one.

#How to Use Comment Moderation Instead of Blocking

To turn on comment moderation in YouTube Studio:

1. Go to YouTube Studio > Settings > Community
2. Under “Defaults,” set comment visibility to “Hold potentially inappropriate comments for review” or “Hold all comments for review”
3. Click Save

YouTube’s comment moderation documentation confirms that you can also add specific words to a blocked words list. Any comment containing those words gets automatically held for review. We tested this with 5 common spam phrases, and it caught about 90% of spam comments within the first week.

If you’re also having trouble with other YouTube issues, check our guides on YouTube error 503, YouTube not working, or YouTube keeps pausing.

#Bottom Line

Block users from their channel page or from any comment they’ve left. Use comment moderation if you’re dealing with widespread spam or harassment. Both features are free and take effect immediately. For YouTube channel management tips or help with sharing private videos, check our other guides.

#Frequently Asked Questions

#Can a blocked user still see my YouTube videos?

Blocked users can’t see your videos or channel when logged into their blocked account. However, they can still view your public content if they log out or use a different account. Blocking doesn’t make your videos private.

#Does YouTube notify someone when I block them?

No. YouTube doesn’t send any notification when you block someone. The blocked user will only notice if they try to comment on your videos or visit your channel and find they can’t interact with it.

#Can I block someone on YouTube without going to their channel?

Yes. You can block someone directly from any comment they’ve left on your videos. Click or tap the three-dot menu next to their comment and select “Block user.” This is often faster than finding their channel page.

#Will blocking someone delete their existing comments?

No. Blocking prevents future comments but doesn’t remove existing ones. You’ll need to manually delete their past comments from YouTube Studio > Comments. You can filter by username to find all comments from a specific user.

#Can I block someone on YouTube from my phone?

Yes. Open the YouTube app, find the user’s comment or channel, tap the three-dot menu, and select “Block user.” The process works the same on both Android and iPhone. The block syncs across all your devices.

#How many users can I block on YouTube?

YouTube doesn’t publish a specific limit on the number of users you can block. In practice, creators have reported blocking hundreds of accounts without hitting any cap. If you’re blocking that many users, comment moderation or restricted mode might be more practical.
