YouTube comment settings most creators never touch

The panel you opened once

The YouTube comment settings are sensible by default, and they are not tuned to your channel. The moderation level, the blocked words list, and the link filter sit in one place most creators open once during setup and never return to. That is how a channel ends up holding nothing, catching spam by hand, and blaming the comment section.

This is a tour of the settings that change how much comment work lands on you, in the order they matter. The behaviour described here is YouTube's, not a product's, and it applies whether you use any tool or none.

What lives where

Two layers of settings exist, and the difference matters when something is not being caught.

Per-video settings control comments on one upload. You can turn them on, pause new comments while keeping the old ones, or turn them off entirely. When comments are on, a moderation dropdown decides what gets held, and a sort order decides what a viewer sees first.

Channel-level settings apply everywhere at once: your hidden users, your approved users, your blocked words, and your link filter. YouTube is explicit that these apply to existing videos and your channel homepage, not only to new uploads. Change them once and they are in effect across the channel.

That is why a blocked word added today can affect a video you published last year. Useful, and worth knowing before you add a broad term.

The four moderation levels

You set a default for new videos, and you can override it on any single video. The dropdown is small, but the choice changes your workload more than anything else here.

| Level | What it does | Who it fits | |---|---|---| | None | Nothing is held. Every comment goes live on arrival. | Channels with very little spam pressure | | Basic | Holds comments YouTube's systems judge potentially inappropriate | The right default for most channels | | Strict | Holds a wider range of borderline comments | News, politics, finance, health, and channels that attract brigading | | Hold all | Every comment waits for your approval | Channels with a community manager, or a specific video under attack |

Basic and Strict are decisions made by YouTube's systems, so they will not always be right. You can approve, remove, or ignore anything they catch. The trade is the familiar one: catch more, review more.

Blocked words

The blocked words list is the setting with the best return for the time it takes, and it is the one most creators leave empty.

Words and phrases you add are compared against comments, including close matches and misspellings. Comments that match are held rather than published. The same list also blocks matching messages in live chat.

Three habits keep the list useful:

• Add phrases, not single words. "free crypto" catches the pitch. "free" catches a viewer asking whether your course is free.
• Add your channel's specific scam. The one that copies your giveaway or quotes your product is the one YouTube's systems have never seen, and the one only you can describe.
• Let it hold, not judge. A blocked-word match is held for review, so a false positive costs you a look at the Held tab, not a lost comment.

The list has a practical size limit, so specificity does more for you than a long list of generic spam words.

Blocked links

Link spam is the highest-volume abuse most channels see, and there is a filter for it. Turning on link holding means comments that contain URLs and hashtags are held for review instead of published.

Two useful details. Comments from you, your moderators, and your approved users are not held, so the filter does not get in your own way. And link filtering applies channel-wide, like blocked words. It is one of the few switches worth turning on the day you learn it exists.

Hidden users and approved users

These two lists are opposite sides of the same idea, and they solve different problems.

Hidden users stop appearing anywhere on your channel. Their comments do not show to viewers and do not show in Studio, and they cannot clip your videos. Use this for the account behind a sustained campaign of abuse, where removing individual comments is a treadmill.

Approved users publish automatically and skip blocked words, blocked links, and the potentially-inappropriate filter. Use it sparingly, for moderators, collaborators, and a small number of long-standing community members whose comments you never want delayed.

The Held tab and the 60-day window

Held comments collect in one place: the Comments page in YouTube Studio, under the Held tab. From there you can approve, remove, report for spam, or hide the user.

The detail that gets forgotten: held comments are kept for up to 60 days. If you do not act on them, YouTube removes them. For spam this is a feature. For a real viewer whose comment was held by an over-eager filter, it is a quiet way to lose a fan who thinks you ignored them.

The practical answer is a review habit rather than a setting. Once a week, clear the Held tab. It takes minutes and it is the difference between a filter that protects you and one that silently deletes your audience.

Sort order

Comments sort by "Most relevant" by default, with relevance shaped by replies and likes, and you can switch a video to "Newest". If your goal is to reply while the audience is still watching, Newest gives you the comments you have not seen yet. If your goal is to shape what a new viewer reads first, Most relevant is doing that work already.

What settings cannot do

The built-in tools are filters, not judgment. They catch patterns: a linked URL, a listed word, a comment a model finds suspicious. They cannot know that the phrase targeting your channel is a scam, that a specific account keeps returning with new display names, or that a comment is the same pitch reworded to slip past the list.

That gap is where the work stays manual, or where a tool earns its place. Local keyword rules in RippleFlow hide on match before the YouTube API is involved, which keeps the filtering free of API quota and adds a channel blocklist for the offenders who change their words. The safety page covers how that pacing and quota tracking work.

Neither approach replaces the weekly look at the Held tab. Change your settings first, then build the habit that keeps real comments out of the queue.
