How to Block People on YouTube: What Actually Happens and What to Expect

Blocking someone on YouTube is straightforward in principle, but the feature works differently depending on where you're interacting with that person, which device you're using, and what you're actually trying to prevent. Understanding the mechanics helps set realistic expectations before you act.

What Blocking on YouTube Actually Does

When you block a user on YouTube, you're restricting how that specific account can interact with you — not with your content globally. Here's what changes after a block:

• The blocked user cannot comment on your videos
• They cannot send you channel messages or replies
• Their existing comments on your videos may be hidden from your view
• They cannot add you to their community posts or tag your channel

What blocking does not do is equally important to understand:

• The blocked user can still watch your videos
• They can still share your content
• Their existing comments may still be visible to other viewers
• They can still subscribe to your channel (though they won't be able to interact with you directly)
• Blocking does not remove their previous comments for everyone — only your view may be affected

This distinction matters a lot. Blocking is primarily a communication filter, not a visibility control.

How to Block Someone on YouTube (Step-by-Step)

On Desktop (Browser)

1. Navigate to the channel of the person you want to block
2. Click the About tab on their channel page
3. Click the flag icon (Report user) in the upper-right area of their About section
4. Select Block user from the dropdown
5. Confirm the action in the dialog box

Alternatively, you can reach the block option directly from a comment they've left on your video by clicking the three-dot menu next to their comment and selecting Block user from channel.

On Mobile (iOS and Android) 📱

1. Tap on the profile picture or name of the user you want to block
2. This takes you to their channel page
3. Tap the three-dot menu (⋮) in the top-right corner
4. Select Block user
5. Confirm

The mobile path is slightly more direct than desktop in most cases, though the exact interface can shift with YouTube app updates.

From a Comment on Your Video

This is often the fastest route:

1. Find their comment on your video
2. Tap or click the three-dot menu next to it
3. Select Block user from channel
4. Confirm

This method is useful when you don't want to visit their channel directly.

Variables That Affect the Experience

Not every block works identically for every user. Several factors shape the actual outcome:

Account type matters. If the person you're blocking operates multiple Google accounts, blocking one account doesn't prevent them from using another to interact with you. Blocking is account-specific, not person-specific.

Creator vs. viewer. If you are a channel owner, blocking has more meaningful effects — it keeps the blocked user from cluttering your comment section and reaching out. If you're a regular viewer blocking another viewer, the practical impact is more limited since you're not managing a shared space they can post to.

YouTube Kids and restricted profiles. If you're managing content through YouTube Kids or a supervised account, the parental controls and content filtering systems operate separately from the standard block feature. Blocking in the standard YouTube app doesn't carry over to YouTube Kids.

Community posts and memberships. If your channel uses Community posts or has a membership tier, blocking a user prevents them from engaging through those channels as well — an important consideration for creators building paid communities.

What Happens to Their Comments After You Block

This is where many users get confused. YouTube does not automatically delete a blocked user's existing comments. What typically happens:

If you want to remove their comments entirely, you'll need to manually delete them from YouTube Studio > Comments — blocking alone doesn't accomplish this.

Hiding Comments vs. Blocking: Understanding the Difference 🔍

YouTube offers a few overlapping tools that are easy to conflate:

• Block user — prevents interaction from a specific account
• Hide user from channel — a softer version; their comments are held for review rather than posted publicly, without notifying them they've been hidden
• Review comments before posting — a broader moderation setting under YouTube Studio that applies to all commenters
• Reporting — flags content or behavior to YouTube for platform-level review (does not block or hide the user yourself)

Hiding a user from your channel is often a more strategic tool for creators who want to silently filter someone without triggering any notification or escalation.

Unblocking Someone

If you change your mind, unblocking is done through your Google account settings under the "People & sharing" section, or within YouTube's account privacy settings. The path is less intuitive than blocking itself — it's not handled directly within the YouTube app in the same obvious way.

The Gap That Determines What You Should Do Next

Whether blocking actually solves your problem depends heavily on what you're trying to protect: your comment section, your personal peace, your community, or something else. A creator managing a large channel with recurring bad-faith accounts faces a very different situation than a viewer dealing with one irritating commenter. The tools exist — but which combination of blocking, hiding, moderating, or reporting fits your specific situation comes down to your channel setup, how active your community is, and what level of control you actually need.
