Fake comments on Facebook ads: aimed at your audience, or bought by a brand

Fake comments under Facebook ads run in two directions: bots and paid accounts posting winners, pitches and one-word praise under your ads, and brands buying praise for their own. As of September 17, 2026, Meta's spam standard forbids "selling, buying, or exchanging for engagement", Moderation Assist can hide new comments from accounts with no picture, friends or history, and Ads Manager hides or reports any comment on the ad.

Below: the two directions with Meta's line on each, what fake comments under my own ads said, the reader's tell, hiding from Ads Manager, Moderation Assist's author criteria, blocking from the Page, why buying praise for your own ads backfires, my numbers, the rule, and Facebook beside Instagram.

Fake comments run in two directions

Against you: accounts that use your ad's reach for their own ends, a fake winner with a link, a review seller, a competitor's plant, a hundred "Good"s from accounts that never bought. Meta's spam standard, read September 17, 2026, calls this content "designed to deceive, mislead, or overwhelm users in order to artificially increase viewership".

By you: praise a brand buys for its own ads, so the thread looks loved. The same standard forbids "Attempting to or successfully selling, buying, or exchanging for engagement, such as likes, shares, views, follows, clicks, use of specific hashtags", and the reader threads that rank for this search are people noticing. Nothing under my ads is bought, and this page says why the trade fails below.

What fake comments under my ads said

Each row is a comment left under one of my Facebook ads between August 1 and September 17, 2026, written as it arrived, the name dropped, the rule that removed it named.

The one-word praise is the shape this search is about, and the hardest for a filter: no link, no number, no profanity. It was removed by hand, and none of the accounts behind it ever commented again.

How to tell an ad's comments are fake

For the reader and the advertiser alike, three checks. Timing: praise for a product nobody could have received yet, under an ad that went live this morning. Repetition: the same sentence, or the same one word, from several accounts, often minutes apart. The profile: no picture, no friends or followers, created this month, a feed of nothing. Moderation Assist offers those last three as switches (the Choose criteria dialog I opened on my own profile on September 8, 2026), no profile picture, no friends or followers, a new profile, which is Meta saying how reliable the signs are.

Hide them from Ads Manager

The route, from Meta's ad-comments page read September 17, 2026: the ad's More options, Manage Facebook comments, and a pop-up with Hide comment and Report comment for a Facebook ad, like and reply beside them. Hide keeps the comment for its writer and their friends and removes it for everyone else; Report sends it to Meta. Deleting is not in the pop-up; it needs the ad's post, opened as the Page. Comments on Facebook ads walks every place an ad's comments can be reached.

Stop them before they land: Moderation Assist

The author criteria above hide new comments from matching accounts "on your Page, profile or ads that you run", and the help page adds a fifth, accounts that "may be using a fake identity". The limit, in Facebook's words: it "only hides comments made after you create the criteria". A bought aged account with a picture and friends passes every one, which is why the link and keyword criteria sit beside them; what Moderation Assist hides and leaves has all twelve.

Block the account from the Page

For the account that returns under every ad, the block is on the Page, not in Ads Manager: Settings, Blocking, Block users, or from the comment itself, hover the name, Options, Block. How to block someone from commenting on your Facebook ads has Facebook's steps and my count of how few ad spammers comment twice.

Why buying praise for your own ads backfires

Three reasons, none of them moral. Meta's rule, above, and the enforcement behind it: Meta's fake-accounts report for the first half of 2026, read September 17, 2026, estimates violating accounts at "less than 5%" of daily active people, and those accounts are what a praise seller delivers, so the praise disappears with them. The reader, who can run the three checks in ten seconds and then reads the whole ad as a lie; the threads that rank for this search are those readers comparing notes. And the thread itself: under an ad for software, four "Good"s in a row from empty profiles look worse than no comments at all.

What my own ads collected

Under my Facebook ads between August 1 and September 17, 2026: 140 comments removed by the link rule, 30 by a custom rule for pitches, 16 by the contacts rule for a pasted phone or bank number, 1 by the impersonator rule, and the one-word praise by hand. Fake comments on Facebook has the six shapes across posts as well as ads.

A rule that removes them in seconds

CommentWatchDog is an AI comment moderation tool that automatically hides and deletes spam and damaging comments on Facebook and Instagram ads and posts. On an ad it acts as the comment lands: the URLs, Contacts and Keywords rules take the winner, the referral and the review seller, a Custom topics sentence takes the pitch, and a single scope setting says whether the rules watch the Page's ads, its posts, or everything; the scope guide explains it. The one-word praise is the honest gap: a rule reads meaning, and "Good" means nothing, so that shape is the profile's to judge.

Common questions

Why do Facebook ads get fake comments?

Because an ad reaches strangers, and a comment under it is read by all of them. A fake winner or a link farm borrows that reach; a review seller sells to the advertiser reading the thread; one-word praise from bought accounts is aimed at the reader, to make the ad look loved. Every one of those shapes has appeared under my own ads since August 1, 2026.

How can I tell if comments on a Facebook ad are fake?

Three checks in ten seconds. Praise that arrives before anyone could have received the product. The same sentence, or the same one word, from several accounts. And the profile: no picture, no friends, created this month. Meta's own Moderation Assist uses the same three signs as criteria, which says how reliable they are.

Does Facebook remove fake comments on ads?

Some. Facebook marks a comment as spam when it looks suspicious or "has been shared too often in a short amount of time", and Meta's fake-accounts report for the first half of 2026 estimates violating accounts at "less than 5%" of daily active people. The comments under your ad are yours to hide, delete, report or block, and Report is the way to tell Meta.

Can I stop fake comments on my ads automatically?

Partly with Moderation Assist's author criteria and the Page's word list; wholly with a rule that reads what the comment means and hides or deletes it as it lands under every ad. CommentWatchDog is an AI comment moderation tool that automatically hides and deletes spam and damaging comments on Facebook and Instagram ads and posts.
