Why you'd want to block YouTube channels
YouTube's recommendation algorithm is designed to keep you watching — not to help you watch better. The result is a feed that fills up with content you never asked for: propaganda from state-sponsored channels, AI-generated videos with zero original value, elsagate-style content that looks child-friendly until it isn't, and scam gurus promising passive income in the thumbnail.
There are three main reasons people want to block specific channels permanently:
- Propaganda and disinformation. Especially relevant for Ukrainian and Eastern European viewers, where Russian state media and its proxies actively push narratives into recommendation feeds. Blocking one channel doesn't stop the algorithm from surfacing the next one.
- AI-generated content farms. Thousands of channels now publish faceless videos using text-to-speech narration and AI visuals. They drown out real creators in search results and flood the homepage.
- Child safety. Kids use YouTube, and the built-in parental controls are either too aggressive (Restricted Mode blocks legitimate educational content) or too limited (YouTube Kids has a narrow library). Parents need category-level filtering, not a binary on/off switch.
The frustrating part: YouTube gives you very little control. Let's go through each option available in 2026.
Method 1: YouTube's built-in "Don't recommend channel"
YouTube has a built-in signal: click the three dots next to a video and select "Don't recommend channel." This tells the algorithm to show you less of this content.
It's a weak negative signal — it reduces frequency but doesn't eliminate the channel, and it forgets after a few weeks. It only works while you're logged in, only on that device, and only on the YouTube website — not embedded players.
Verdict: Good for one-off dismissals. Useless for systematic filtering.
Method 2: Manual blocking
YouTube's real "Block" feature is buried and built for harassment protection, not content filtering. Blocking a channel only stops it from interacting with your channel — it does not remove their videos from your feed or search results.
Verdict: Solves a different problem entirely.
Method 3: Browser extensions
For years the power-user approach was extensions that manipulate the YouTube DOM and hide blocklisted channels.
BlockTube (discontinued). Once the most popular option — block by ID, handle, or keyword regex. The problem: it hasn't been meaningfully updated since 2024, has 438 open GitHub issues, and is built on Manifest V2, which Chrome retired in 2025-2026. Effectively dead for most users.
Unhook. Hides YouTube's recommendation UI entirely — no sidebar, no homepage feed, no end screens. Great if you use YouTube like a search engine, useless if you still want a filtered feed.
Verdict: The right category — but existing options are either dead or too blunt.
Method 4: Blokari — curated lists for 2026
Blokari is a Manifest V3 Chrome extension built specifically for systematic content filtering. Unlike BlockTube, which made you build a blocklist one channel at a time, Blokari ships with curated lists of 10,000+ channels in 14 categories.
You install the extension, choose categories, and Blokari hides matching channels across your feed, search, subscriptions, and related videos. Lists update regularly. You can add custom channels and keep a personal whitelist.
There's also a second layer most blockers miss: Blokari can automatically send YouTube's own account-level "Don't recommend channel" signal for the channels you block. Because that signal lives on your Google account, it follows you to devices where extensions can't run — the mobile app and TV — and gradually reduces those channels there too. So you hide them on desktop and train them down everywhere you're signed in.
Getting started:
- Install Blokari from the Chrome Web Store (Chrome, Edge, Brave).
- Open the popup by clicking the Blokari icon.
- Choose your categories — Propaganda, AI content, Kids trash, Info-scams, Clickbait, Gambling, and more.
- Set your filter level per category — Flag (blur + badge), Block deception, or Block all.
- Reload YouTube. Channels from your selected categories are now hidden. No account required for basic use.
Blokari is free for all core features including the full database and parental controls. Pro ($3/month) adds daily sync and recommendation training.

FAQ
Can you block a YouTube channel permanently?
YouTube's built-in tools only reduce a channel's frequency and forget over time. For permanent blocking you need a browser extension like Blokari that hides channels across your feed, search, and recommendations and keeps them hidden.
Does "Don't recommend channel" actually block the channel?
No. It is a weak negative signal that YouTube gradually forgets. The channel still appears in search, related videos, and on its own page, and it only works while you are logged in on that device.
What happened to BlockTube?
BlockTube is a Manifest V2 extension. Google deprecated MV2 and removed support throughout 2025-2026. BlockTube has not migrated to MV3, has 438 open issues, and no longer works reliably in Chrome Stable. See our full guide to BlockTube alternatives.
Is Blokari free?
Yes. The full blocking database, all platforms, and parental controls are free. The Pro plan ($3/month) adds daily list sync and recommendation training.
