Need a list to copy and paste right now? The free Blocked Words Generator has 480+ phrases in eight categories that you can toggle, edit, and copy into YouTube Studio as one comma-separated line. For narrower lists, the moderation pack library covers impersonation, giveaway scams, subscription exchanges, and Spanish spam, each with a phrase checker and examples of legitimate comments that can also match.
Short answer. Start your YouTube blocked words list with clear scam and abuse terms, keep gray-zone words on a review-only watchlist, and skip broad words that catch real fans. Paste the list into YouTube Studio under Settings, Community moderation, Content controls, separated by commas. Matching comments are held for review, so check the Held tab and prune the list monthly.
Most channels do not have a spam problem, they have a filtering strategy problem. If your blocked words are too light, scams leak through. If your list is too broad, you suppress real viewers and hurt engagement quality.
This guide gives you a practical blocked-words framework you can implement in under an hour. It is designed for solo creators and teams managing high comment volume.
How YouTube Blocked Words Actually Work
Use YouTube Studio moderation settings as the baseline. Official references: comment settings, spam and held comments, and blocked words controls.
- Blocked terms route comments into moderation flow rather than blind trust.
- False positives increase when lists include generic terms like "link" or "free" without context.
- Your highest-signal tuning data lives in held comments and resolved moderation actions.
Blocked Words vs. Banned Words: Where to Add Them
Many creators search for a YouTube "banned words list." YouTube doesn't publish one. What you're looking for is your channel's own Blocked words setting, a list you write yourself. Comments that contain one of your words are held for review instead of going live, and they stay hidden unless you approve them.
- On a computer: sign in to YouTube Studio, click Settings, then Community moderation, then Content controls. Add your words and phrases to Blocked words, separated by commas, and click Save.
- In the YouTube Studio app: tap your profile picture, then Settings, and under Community tap Content controls to reach the same Blocked words field.
- What it covers: the same list applies to comments, live chat, and posts in your Community.
Those steps come from YouTube's guide to managing your channel's moderation settings. Held comments wait in the Held tab of YouTube Studio's Community page, so check it after you add a new batch of words. Our guide to YouTube comments held for review covers clearing that tab faster.
Starter Blocked Words Categories
Use categories instead of a random giant list. This keeps maintenance fast and easier to explain across a team. Our Blocked Words Generator gives you 480+ pre-sorted terms across eight categories you can toggle, customize, and copy straight into YouTube Studio.
- Impersonation and scam intent: fake support claims, WhatsApp/Telegram contact funnels, account recovery bait.
- Abuse and harassment terms: high-severity slurs and direct threat language.
- Adult and explicit solicitation: obvious sexual spam and escort-like bait patterns.
- Fraud promo patterns: investment guarantees, crypto pump language, payment urgency scripts.
- Link abuse patterns: suspicious URL fragments and known scam call-to-actions.

What Not to Block
Over-blocking is the most common creator mistake. Avoid broad terms that are normal in legitimate comments.
- Do not block common product terms your audience naturally uses.
- Do not block neutral words that appear in genuine questions.
- Do not block based on one incident. Put uncertain terms on a review watchlist first.
Monthly Maintenance SOP
- Export or review held comments from the last 30 days.
- Tag false positives and remove their trigger terms.
- Add only recurring high-confidence abuse patterns.
- Review with one owner, then publish changes in one batch.
- Track impact by false-positive rate and moderation queue volume.

Use AI Rules for Gray-Zone Comments
Text filters handle obvious abuse. Gray-zone comments are better handled with AI classification and approval flows. Blocked words match text, not meaning, so a scam that changes its wording slips past them. Automatic YouTube comment moderation with CommentShark can match comments by meaning, then hold them for review, delete them, or email you about them, and you can keep each rule on approval while you tune it. If you are weighing other options, our comparison of YouTube comment moderation tools shows what each one can do to a YouTube comment.
