How to Block Someone on YouTube on Desktop and Mobile

Blocking someone on YouTube is quick once you find their channel, comment, or live chat message. Once blocked, that person can’t interact with you through comments, live chat messages, or mentions tied to that account. 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, blocking a channel stops comment, live chat, and mention interactions tied to that account. The same Google Help page states that the blocked account is also blocked in other Google products.

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 restored interactions across desktop and mobile sessions on the same Google account after the block list refreshed.

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 while the user is signed in to the blocked account. If they sign out or switch to 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 states that channel comments can use 4 moderation levels: none, basic, strict, or hold all. The same page says comments containing blocked words or links can be reviewed under the Held tab for up to 60 days, which gives you a more scalable filter than blocking one account at a time.

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

Playback hiccups during long viewing sessions often have separate causes, so our walkthrough on YouTube keeps pausing covers those triggers in more depth.

#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.
