The short version: Comments on TikTok disappear because of automatic filtering, not usually because of some grand shadowban conspiracy. TikTok's spam and keyword filters catch far more than actual spam, your own filtered keywords list is probably switched on without you knowing, and app caching bugs make comments look gone when they're not. Fix it by checking your comment settings first, then your filtered words list, then the app itself, in that order.
The moment I first noticed it
A client of mine, a bakery owner in Kent with about 40,000 followers, posted a video showing how she decorates a wedding cake. It did well, 280,000 views in three days, and the comments were flying in. Then she messaged me confused because her comment count said 412 but she could only scroll through about 90 of them. She thought TikTok was broken. It wasn't broken. It was doing exactly what it's designed to do, quietly.
That's the bit nobody tells you upfront: TikTok removes and hides far more content than it ever shows you a notice for. There's no popup that says "we deleted 300 comments on your video." They just vanish, and you're left assuming the worst, usually that you've been shadowbanned, when the real answer is far more mundane.
The real reasons comments disappear
Automatic keyword and spam filtering
TikTok runs every comment through automated moderation before it's fully visible. Comments containing flagged words, even mild ones like "dead" or "kill" used in slang ("that outfit killed it"), can get auto-hidden or held for review. This is the single biggest cause of vanishing comments and it happens without any warning to the commenter or the video owner.
Your own filtered keywords list
Inside Settings and Privacy, under Comments, there's a filter for keywords. You can add up to 100 words or phrases that TikTok will automatically hide from your comment section. I've lost count of the number of creators who set this up months ago, forgot about it entirely, and then panic when comments containing perfectly normal words never show up.
The commenter is restricted or shadow-limited
If the person commenting has had strikes on their own account for community guideline violations, their comments can be limited in visibility even on other people's videos, regardless of what the comment says. It's their account history causing the problem, not yours.
App caching and sync bugs
Sometimes comments just fail to render. This tends to happen alongside other glitches, like the app freezing or videos failing to load, which I've covered in detail in why TikTok isn't loading and how to fix it. A stale cache is a much more boring explanation than a shadowban, but it's a common one.
Comments were deleted by the person who wrote them, or by TikTok's own bulk sweeps
TikTok periodically runs mass moderation sweeps, particularly after policy updates. In past transparency reporting periods TikTok has said it actions tens of millions of pieces of content and interactions each quarter for guideline violations. Your comment section can get swept up in that even if nothing on your video looks obviously wrong.
Your account has a restriction on it
If your account is under review, has had a recent strike, or is flagged for unusual activity, comment visibility across your videos can drop noticeably, similar to what happens with likes. I've written separately about why TikTok likes sometimes disappear because the two problems share several of the same causes, mainly account-level trust signals dropping.
The uncomfortable bit most people skip past
Here's the part that annoys creators when I say it out loud: a lot of vanishing comments are the direct result of engagement tactics creators were told to use. "Comment your favourite colour below," "reply with an emoji if you agree," pods where groups of creators comment on each other's videos within minutes of posting, all of that pattern-matches almost exactly to what TikTok's spam detection is built to catch. Repetitive short comments, comments arriving in tight clusters from accounts with no other activity on your videos, comments from accounts that only ever interact with each other, that's textbook spam behaviour to a filtering system, even when the humans behind it are real.
So the same growth advice that gets shared in every "how to boost your TikTok engagement" thread is quietly training the algorithm to distrust your comment section. Nobody wants to say that because it means admitting the tactic doesn't just risk looking cheap, it risks actively costing you the comments you worked to get.

What to check, step by step
- Step 1: Check your comment settings. Go to Settings and Privacy, then Comments. Confirm who can comment isn't set more restrictively than you intended, and check whether comment filtering is set to Strong instead of the default.
- Step 2: Check your filtered keywords list. Same menu, look for the keyword filter section. Clear it out if you don't remember setting it, or trim it down to offensive terms only.
- Step 3: Log out and back in. This clears a surprising amount of local caching issues that make comments appear missing when they're just not syncing.
- Step 4: Update the app. Comment bugs get patched quietly in updates far more often than TikTok publicly announces.
- Step 5: Check for a violation notice on your account. Go to Settings, Account, and look for any account status or violation history. A recent strike explains a lot.
- Step 6: Ask the commenter to check their own account. If it's one specific person's comments disappearing, the restriction is likely on their end, not yours.
- Step 7: Wait 24 to 48 hours before assuming it's permanent. A chunk of moderation actions are temporary holds while automated systems double check, and comments do reappear.
How this connects to your bigger TikTok picture
Comments don't disappear in isolation. They tend to disappear alongside softer engagement, quieter notification bells, and slower view counts, which is why creators frequently notice all of it at once and assume something dramatic has happened to their account. If you're also missing alerts entirely, it's worth reading why TikTok notifications sometimes stop working because the two issues often share a root cause in app permissions or account flags rather than being separate problems.
It's also worth remembering that comment count is one of the smaller signals in TikTok's ranking system compared to watch time and shares, but it's still a visible trust signal to anyone landing on your video for the first time. A video with 200,000 views and only 12 visible comments looks strange to a stranger scrolling past, even if the real number was 400 before filtering. That mismatch between what the algorithm sees and what a viewer sees is one reason accounts with engaged audiences pull ahead, something I go into more in why some TikTok accounts get more likes than others, because likes and comments both live or die by the same trust signals.
What I'd do if I were you
Stop treating every missing comment as a mystery and start treating your comment section like a setting you own, because it is one. Check the filter list monthly, particularly after any big policy update TikTok announces. Stop chasing comment-bait tactics that mimic spam patterns, because they cost you more than they gain once filtering kicks in. And if a specific comment matters, from a customer, a journalist, a brand you're trying to work with, screenshot it the moment you see it. Don't rely on it staying visible, because the platform makes no promises that it will.
My bakery client's comments came back, most of them, within about three days, once she cleared a keyword filter list she'd set up over a year earlier and forgotten about entirely. No appeal, no support ticket, just a five minute settings check she should have done on day one.
Frequently asked questions
Why do my TikTok comments disappear only on certain videos?
It's usually because those specific videos triggered stronger automated moderation, either from the words used in the comments, the speed and pattern of comments arriving, or a spike in reports on that video, rather than anything wrong with your account overall.
Can I get deleted TikTok comments back?
If they were held by an automated filter rather than permanently removed, they can reappear within 24 to 48 hours. If the comment violated guidelines and was permanently removed, there's no way to restore it, and TikTok doesn't send a notification either way.
Is TikTok shadowbanning my comments?
Almost always no. What looks like a shadowban is nearly always a filtered keyword list, an account restriction on the commenter's side, or an app syncing bug, all of which are fixable through settings rather than an unexplained, unappealable ban.
Why do comments disappear right after I post them?
This is typically the filtered keywords setting catching a word you didn't expect, or the comment being flagged instantly by TikTok's spam detection because it matched a pattern common to bot or engagement-pod comments, even if a real person wrote it.
