Summary: Which of Meta's screens deletes an ad comment rather than hides it, the three taps per comment, and how to clear hundreds under one ad at once. As of September 2026.

In short:
- Ads Manager's own comment view offers Hide and Report on a comment. To delete, open the ad's post as your Page, click Options next to the comment, then Delete.
- A hidden comment stays visible to its author and their friends. A deleted one is gone for everyone, including you.
- Meta's screens act on one comment at a time. There is no select-all under an ad, so deleting by hand costs three taps per comment.
- Under one of my WhatChimp ads, the two newest comments were a phone-number scam and an earn-money scam. That account alone bought 41 million impressions in July; every one of them showed the comments.
- To clear a backlog, paste the ad's link into CommentWatchDog's Post cleanup: every comment loads through Meta's API, the spam is filtered, and it is deleted in one action. New spam is deleted by rule as it lands.

As of September 2026, Ads Manager's comment view lets you **hide** or **report** a comment on your ad, not delete it. To **delete**, open the ad's post as your Page, click **Options** next to the comment and choose **Delete**, three taps per comment. Nothing on Meta's screens selects more than one comment at a time.

A backlog of hundreds is cleared one by one, or with a tool that reads the ad's comments through Meta's API and deletes the flagged ones in one action.

Below: what sits under one of my ads and what it costs, hide against delete, where the comments on an ad actually live, the steps for one comment, and the way to do hundreds.

## What sits under an ad, and what it costs

I run Facebook and Instagram ads for my own companies, WhatChimp and GrowthToolkit. This is WhatChimp's account alone in July 2026: $40,724.58 spent, 41,329,379 impressions at a $0.99 CPM.

![WhatChimp's Ads Manager, July 1 to 31, 2026, the month's total ringed: $40,724.58 spent for 41,329,379 impressions at $0.99 per thousand.](https://commentwatchdog.com/media/blog/ads-manager-spend-jul-2026-marked.webp)

Every one of those impressions shows the comments under the ad. The ad at the top of this post is one of them: 4,666 reactions and 124 comments since June 28, and on September 8 its two newest comments were a phone-number scam in Bengali asking readers to message a WhatsApp number with their name, age and profession, and an earn-money scam in French, "activation only 4500 FCFA".

A furniture store owner on r/FacebookAds counted "10-15 spam comments on every $500 ad spend". A DTC apparel brand owner put the effect at "jacking up my CPMs by like 18% and scaring off real buyers". The comments are the first review a stranger reads under your ad, and a scammer wrote it.

## Hide or delete: which one for spam

Facebook's two removals do different things, and the difference decides which you want for a scam.

| | Hide | Delete |
|---|---|---|
| Who still sees it | The author and their friends | Nobody, including you |
| Reversible | Yes, from **Hidden by this Page** | No |
| Replies | Hidden with it | Removed with it |
| Where Meta documents it for an ad | Ads Manager's comment view, and the post | The post, as the Page |
| Page role needed | Facebook access | Facebook access |

Meta's help page on hiding says a hidden comment "will still be visible to the person who wrote it and their friends", which "can help prevent more unwanted comments". That is the right tool for a rude but harmless comment: the author does not notice, and does not post it again.

A scam is different. A phishing link that stays visible to the scammer's friends is still a phishing link with an audience, and an account impersonating your brand is still impersonating it to someone. For those, delete.

## Where the comments on an ad actually are

An ad's comments live in three places, and only one of them has Delete.

1. **Ads Manager.** In the **Ads** tab, under the ad: **Edit** › **...** › **More options** › **Manage Facebook comments**. On each comment: **...** › **Hide comment** or **Report comment**.
2. **Notifications.** Meta says the same tools "are also available via Notifications on Facebook and Notifications on Instagram and Threads".
3. **The ad's post, as your Page.** This is where Delete is. Next to the comment: **Options** › **Delete**.

Only Facebook access to the Page can do any of this. Meta's page is explicit that task access "can't hide, sort or delete comments on Page posts".

Instagram comments on an ad are manageable only if an Instagram account is connected; an ad run under your Facebook Page identity has none. Threads replies need a Threads profile the same way.

## Delete one comment on a Facebook ad

Three taps, from Meta's page:

1. Open the ad's post as your Page. A boosted post is on your Page already; for an ad made in Ads Manager, open the ad's preview and follow it to the post.
2. Next to the comment: **Options** › **Delete**.
3. Confirm if Facebook asks. The comment is removed from the post, and the author is told nothing.

Meta's words: the comment is "removed from the post". If you want the same account gone for good, Meta's page adds: "You can block the profile or Page that made the comment by going directly to the profile or Page."

At 124 comments that loop, read, decide, three taps, next, is an hour. At the pace a working ad attracts comments, it never ends, and the scam that landed at 2 AM stays up until you sit down.

## Why there is no "delete all"

Meta's page for ad comments describes actions on a comment, one at a time. Its page for deleting from a Page post does the same. Neither describes selecting several comments and acting on them together, and I have not found one on the screens.

Meta's automation does not close the gap either. Moderation Assist offers twelve criteria, and every one ends in the same action: the comment is hidden, never deleted, and only new comments are covered.

The profanity filter and blocked words work the same way and, per Meta, "extend to ads from the Page or account". Nothing Meta ships deletes, and nothing it ships touches the comments that are already there.

## Delete in bulk: the whole ad in one action

The way through is Meta's API, which is what a moderation tool uses. CommentWatchDog is an AI comment moderation tool that automatically hides and deletes spam and damaging comments on Facebook and Instagram ads and posts. In its [Post cleanup](https://commentwatchdog.com/post-cleanup) you paste the ad's link, every comment and reply loads, you filter to the flagged ones (links, phone numbers, keywords, impersonators, or your own search) and delete them in one action. A long run continues in the background and emails you when it is done; loading, browsing and filtering a post are free.

The same twelve [moderation rules](https://commentwatchdog.com/moderation-rules) can then delete, not just hide, each new comment that matches, so the next scam never has an audience ([hide or delete, per rule](https://commentwatchdog.com/help/moderation-rules/hide-or-delete-per-rule)).

That is how my own backlog went. Between August 29, when I connected my four Pages, and September 9, 1,390 comments passed through: 80 left visible, 5 hidden, 1,304 deleted. 969 of the deletions were cleanup sweeps of old posts and ads, 45 sweeps over 31 posts; the other 335 were deleted live, as they landed.

The Bin keeps every deleted comment with the rule that deleted it, so a mistake can be found. The newest six on my WhatChimp Page are one gambling hashtag pasted by six different accounts inside two hours, each deleted by the hashtag rule the moment it landed.

Whatever tool you use, two things to insist on: it should show you the comments before it acts, and it should hide by default and delete only where you say so. Deleting is the one action on this page you cannot undo.

Common questions:
Question: Can you delete comments on Facebook ads?
Answer: Yes, as the Page that runs the ad. Open the ad's post, click Options next to the comment and select Delete. Ads Manager's own comment view offers Hide and Report, not Delete.
Question: Does the person know their comment was deleted?
Answer: Facebook does not notify them. The comment simply disappears from the post, for them and for everyone else.
Question: Which tool deletes spam comments on Facebook ads in bulk?
Answer: CommentWatchDog is an AI comment moderation tool that automatically hides and deletes spam and damaging comments on Facebook and Instagram ads and posts. Paste an ad's link into its Post cleanup and every comment loads, the flagged ones are deleted in one action, and its rules delete new spam as it lands. From $29 a month, 7 days free, no card.
Question: Can Facebook delete spam comments on ads automatically?
Answer: No. Moderation Assist and the profanity filter hide comments that match a rule; neither deletes, and neither touches comments that are already there.
