Automatic AI Comment Moderation on YouTube

ZenFeed keeps comment sections in order on Facebook and Instagram today. And the question we hear most often from brands, newsrooms and organizations is: “when X? TikTok? YouTube? Telegram?“.

We didn’t want to answer on instinct, so we reviewed the four biggest platforms through the lens of three questions:

How do they approach fighting hate and disinformation — do they treat comments as an area worth defending at all?
What moderation tools do they offer — and, more importantly, can those tools be automated through an API?
Do they cooperate with law enforcement, and how — because some of what looks like hate speech is in fact a crime, and then an entirely different channel matters.

The short answer: YouTube will be the next platform in ZenFeed. Below we explain why — and what we do where automated moderation is technically impossible. Because there is a way to handle that too, and it’s a good one.

How we evaluated the platforms

ZenFeed is a single, repeatable loop: a comment appears under a publisher’s content → the system evaluates it for context, not a list of banned words → if it crosses the threshold you set, it gets hidden or removed in about 3 seconds. To recreate that loop on a new platform, you need three things: access to comments (webhooks or polling), the ability to act (hide/delete), and predictable API terms. Where any of those elements is missing, a third path remains — a well-drafted removal request or a referral to law enforcement. We write about that path too, because it applies to not one but two platforms on this list.

X: “free speech, not free reach” — and the most expensive API in the lineup

Since the change of ownership, X has championed the “freedom of speech, not freedom of reach” policy: instead of removing content, it labels it and limits its reach, making Community Notes its flagship tool against disinformation. That approach has a price — research documents a rise in hate speech on X after its moderation rules changed, as we covered in our analysis of why comment sections turn toxic — and in December 2025 the European Commission imposed the platform’s first fine under the DSA: €120 million for a deceptive blue-check verification system, shortcomings in the ads repository and obstructing researchers’ access to data. X did sign the updated EU Code of Conduct on countering illegal hate speech (Code of Conduct+) in January 2025, but enforcing its own rules can be unpredictable.

And the tools? An account owner can hide a reply under their own post, block an author, mute words. But those are manual tools for a single person — with no automation at the level of a brand account or a team. Technically, X’s API can hide a reply on the author’s behalf, but access is paid under a pay-per-use model (since 2026; earlier subscription packages ran from $100 to $42,000 per month) and can change without notice. Building protection that someone’s mental health depends on, on foundations whose price and rules get rewritten every few months, is a bad investment. X does cooperate with law enforcement — it publishes transparency reports and fulfils legal requests — though it appealed the DSA fine in February 2026.

Verdict: we wait until X’s API stops being a moving target.

TikTok: strong moderation from the center, zero API for creators

TikTok runs the most centralized moderation of the four. The platform itself removes the vast majority of rule-breaking content before anyone reports it — that’s what its transparency reports show. In the EU it signed Code+ and has already published its first report under that code (May 2026). It fights disinformation with labels, state-media designations and fact-checking partnerships.

Creators aren’t helpless, though — just manual. TikTok offers a keyword filter, holding all comments for approval, and bulk deletion in TikTok Studio. The problem is that there is no public API at all for reading, hiding or deleting comments on organic videos — the only endpoints concern comments under paid ad campaigns. There are no webhooks either. An automation you can’t plug into is an automation you can’t build — no matter how hard we try. Cooperation with law enforcement exists and is formally documented (guidelines for authorities, reports on data requests), but that changes nothing about the tooling.

Verdict: no moderation integration — for now. But see the section on reporting, because TikTok isn’t a lost cause.

YouTube: the full toolset, the full API, and the only real equivalent of “hide”

YouTube combines automated classification with de-amplifying borderline content (it pushes it out of recommendations even when it doesn’t break the rules), fact-check information panels and designations. And above all: it treats comments as a first-class moderation surface — not an afterthought.

Within the app itself, YouTube Studio lets you hold potentially inappropriate comments for manual review, maintain blocked-words lists, hide users and work through the “Held for review” queue. Done manually, this works well — until the comments number in the thousands.

But what sets YouTube apart lies outside the app. The YouTube Data API has a full set of comment operations: reading threads (including with a moderation status filter), setting a status (published / heldForReview / rejected / likelySpam), deletion, and replies. The mapping onto ZenFeed’s model is almost perfect: heldForReview is a real “hide” — the comment disappears from public view but isn’t deleted and can be restored. There are no webhooks for comments, so we work like any serious pull-based integration: periodic polling, a cursor, a quota budget (10,000 units per day by default; a moderation action costs 50). Access to the required OAuth scope comes with an annual security audit on our side — the equivalent of the Meta App Review process we know well, just repeated every year. We accept that cost.

Google publishes transparency reports, maintains guidelines for authorities, and is a Code+ signatory in the EU. No surprise: with billions of comments a year, YouTube had the most to lose from not taking moderation seriously.

Verdict: the next platform in ZenFeed.

Telegram: minimal tools, an open Bot API, and a new era of law-enforcement cooperation

Historically, Telegram left order to group admins and was notorious for slow responses to reports. The DSA forced a change: the platform published guidance for EU users, launched a form for reporting illegal content, and started issuing transparency reports. After Pavel Durov’s arrest in France (August 2024), Telegram noticeably accelerated its cooperation with authorities — today it reports on that cooperation regularly, whereas before 2024 responses to requests were a rare exception.

Comments under a public Telegram channel are actually messages in a linked discussion group, and admin tools are basic: delete, ban, slow mode. But Telegram’s Bot API is free, open and mature — a bot with administrator rights in the discussion group can receive and delete comments in real time. That’s a real path to automated moderation under channels, technically simpler than YouTube, though with a smaller volume among our current customers.

Verdict: candidate number two.

What about a platform that offers no tools at all?

TikTok shows that being a massive platform doesn’t mean giving publishers any API at all. But the absence of automated moderation doesn’t mean the absence of options. There are two — and both can be automated:

A well-drafted removal request. Every major platform has a mandatory mechanism in the EU for reporting illegal content (Article 16 DSA). A notice that contains a link, a quote, a timestamp and a clear explanation of why the content is illegal gets processed faster and more effectively than a context-free click on “report”. Telegram runs a dedicated form for this; X, TikTok and YouTube have their own channels. ZenFeed can prepare such notices automatically — at the same pace it evaluates comments today, with the same care for context and legal qualification.
A referral to law enforcement. Under Polish criminal law, threats, stalking, incitement to hatred and defamation are crimes. For such content, a complete referral can be prepared automatically: collected evidence (links, quotes, dates), legal qualification and a description of the scale. A human always decides whether to send it — but the paperwork that discourages most victims today disappears.

This isn’t as good as removing hate speech in 3 seconds. It does, however, turn an “unmoderatable” platform into a process: repeatable, documented, scalable. And — as always in ZenFeed — this path applies exclusively to illegal and clearly harmful content, not to criticism or disagreement. The line between criticism and harm is something we deal with every day.

ZenFeed’s position: we set the order by reality, not by noise

YouTube wins in all three categories: the fullest toolset for channel owners, the only complete API for comment moderation, and predictable — though not cheap — access terms. Behind it we place Telegram, thanks to its open Bot API. Where X and TikTok land depends on two things: the stability of X’s API terms, and demand from you.

Because no platform will fix this for you — not for a billionaire with a law firm, and not for the admin of a local fan page. Since we are the ones who live with the comments, we are the ones who get to choose the protection we want.

Key takeaways

All four platforms have rules against hate speech, but only YouTube gives channel owners both a full toolset and a complete API for automated comment moderation.
X: a “free speech instead of reach” policy, a €120 million DSA fine (December 2025) and a paid, unstable pay-per-use API — for now, a poor foundation for a product.
TikTok: strong central moderation and decent manual tools, but no public API for organic comments — automated integration is impossible.
Telegram: after 2024 it clearly increased cooperation with law enforcement and implemented its DSA obligations; the open Bot API makes it a real candidate for number two.
Where there’s no API, we’re not helpless either: well-drafted removal requests (including under Article 16 DSA) and referrals to law enforcement can be prepared automatically.
Verdict: YouTube will be the next platform in ZenFeed.
