Review bombing: what it is, and what the platforms do about it
A wave of 1-star reviews in a day or two feels like an attack. Sometimes it is. Sometimes it is a real failure that reached many customers at once. The first job is to find out which, because the right response is different, and the wrong one can cost you your TrustScore. When it is an attack, we remove the reviews that break Trustpilot's rules, and you pay per removal.

100% risk-free. You only pay for the reviews that come down.
Short answer
Review bombing is a sudden flood of low ratings driven by something other than ordinary trade. First work out whether it is an attack or a real failure, by checking those dates in your own shipping, billing and support records. If it is real, fix the cause and say so in public. If it is an attack, document it and flag only the reviews that break a named rule, a few at a time. Bulk flagging and counter-review drives both make it worse.
Key facts
Trustpilot lists flagging reviews in bulk over a short period as misuse, so mass-flagging a wave of reviews can make things worse.

Trustpilot's rules do not allow reviews written solely about a topic trending in the news or on social media, without a genuine experience.
Trustpilot may add a Consumer Alert to a profile that is getting significant media attention. An alert is information, not a penalty.

Asking friends, staff or customers for counter-reviews to drown out the wave breaks Trustpilot's rules and the FTC's Consumer Review Rule.

Yelp is the only major platform with a published review-bombing policy: an Unusual Activity Alert, with posting temporarily disabled.
What each platform does about a wave
Three platforms, three different answers, and only one of them is written down properly.
| Platform | Published policy for a sudden wave | What it does |
|---|---|---|
| Yes, in a blog post and a policy page | Removes spam, pauses new reviews on the profile, alerts the owner, shows consumers a banner | |
| Yelp | Yes, and in the most detail | Places an Unusual Activity Alert and temporarily disables posting |
| Trustpilot | None | Per-review automated detection of unusual patterns, and a Consumer Alert for media attention |
Google. Its 2026 post on protecting businesses on Maps sets out what happens on a sudden spike in spam reviews. Google says it will quickly remove the fake content, pause new reviews on the profile, alert the Business Profile owner, and show consumers a banner explaining the pause. Its posting restrictions policy covers the same ground more formally. Google says it may limit or suspend user-generated content for a place after a spike in irrelevant or offensive content, and lifts the restriction when the abuse subsides.
What Google does not publish is any number. No threshold for what counts as a spike, no duration for a pause, and no way for a business to ask for one. The same post reports Google's 2025 volumes: more than 292 million policy-violating reviews blocked or removed, against more than a billion published. Those and the other platform figures are on our online review statistics page.
Yelp. The most documented of the three. Its Consumer Alerts page says that an unusual spike in activity on a business page brings an Unusual Activity Alert, with posting temporarily disabled. Yelp says moderators remove the alert and clean up the page when activity returns to normal. It runs a separate Public Attention Alert for waves that follow an accusation against someone connected to the business. Yelp also states plainly that reviews written as social commentary are not useful to people relying on Yelp.
Trustpilot. Nothing. We looked. Its help centre and legal pages carry no page on review bombing, review storms or sudden spikes. Its Action We Take document does not use the words coordinated, spike, surge or influx. What it does publish is per-review: its detection technology checks new reviews before they appear and flags unusual patterns. There is no profile-level pause and no consumer-facing notice that a flood happened.
That absence shapes what you can do. On Google and Yelp, part of the answer is waiting for a mechanism that exists. On Trustpilot, the whole answer is the work below.
Step 1: attack or failure?
Look at your own data for the same 48 hours before you decide anything.
| Sign | Points to a real failure | Points to an attack |
|---|---|---|
| Your records for those dates | A shipping, billing or pharmacy incident | Nothing unusual |
| What the reviews describe | The same real problem, in different words | A news story, a social post or no experience at all |
| Reviewer accounts | Mixed ages, other reviews on other companies | Many new accounts with one review each |
| Wording | Varied, with order details | Near-identical phrases |
| Support inbox | A matching spike in tickets | No spike |
| Labels | Some Verified or Invited | All Unprompted |
Many waves are partly both. A real incident gets picked up on social media, and people who were never customers pile on.
Health brands should expect the real-failure case more often than they would like. A cold-chain failure, a pharmacy backorder or a billing run that charged cancelled accounts reaches hundreds of customers in a day. See why telehealth brands get more 1-star reviews.
Step 2: if it is a real failure
These reviews are genuine experiences. They stay, and flagging them is misuse.
- Fix the cause and say so. A short public statement on your site, and an email to affected customers.
- Reply to each review once, in general terms, with a private channel. Health brands must not confirm that anyone is a patient. See HIPAA-safe replies.
- Apply your refund policy without conditions. Never tie a refund to a review. Trustpilot treats that as an incentive, and the FTC named it in its NextMed case.
- Keep inviting every customer in the normal way. TrustScore weighs recent reviews most, so a fixed process shows up in the score over the following weeks.
Step 3: if it is an attack
Document before you act
Capture each review: a screenshot, the link, the date, the reviewer's profile and review count. Note what ties the reviews together, such as the post that started it. Our guide on how to document a fake review has a log format.
Know which rules the reviews break
| What you see | Trustpilot rule that may apply |
|---|---|
| Reviews about a news story or social media topic, with no experience of your service | Advertising or promotional: reviews written solely about trending topics |
| Reviewers who say they never used you | Not based on a genuine experience |
| Reviews that promote a competitor or a link | Advertising or promotional |
| Threats, hate speech, staff named with contact details | Harmful or illegal, or personal information |
| Negative opinions from real customers who joined in | No rule. These stay |
Source: Trustpilot's flagging reasons. Trustpilot's reviewer rules also say a person cannot review a topic that is trending in the news or on social media. Our guide to how Trustpilot defines and detects fake reviews covers the proof that works.
Flag carefully, not quickly
This is the hard part. Trustpilot lists flagging in bulk over a short period as misuse, because it suggests targeting by sentiment. Its automated systems also scan for flagging abuse. A team that flags eighty reviews on a Monday morning can end up with a warning on top of the attack.
- Flag the clearest breaches first, a few at a time.
- Use the right reason for each review and highlight the exact words.
- For genuine experience cases, send the Request information step first. It is required.
- Do not re-flag reviews Trustpilot has decided to keep.
Tell Trustpilot about the pattern
Trustpilot says anyone can report suspicious behavior through its contact form and that it investigates reports sent through its whistleblower function. A short, factual report with your evidence of coordination is worth sending. Trustpilot does not publish how it handles a specific surge, so we do not describe one.
Expect a Consumer Alert
If the wave follows press coverage, Trustpilot may place a Consumer Alert on your profile to tell readers the business has had significant media attention. An alert does not mean you did anything wrong. It is different from a Consumer Warning, which is for misuse. Our Consumer Warning guide explains both.
Step 4: if the wave is on Google
The work is the same shape, and three things differ.
Report one by one, with the right policy. Google removes reviews that break one of its content policies and keeps the rest. A wave driven by a news story usually falls under off-topic or spam, and reviews from people who were never customers fall under fake engagement. Our guide to spotting and reporting a fake Google review lists the evidence to gather first. Our guide to reporting a Google review covers the grounds and the form, and there is one appeal per decision, covering up to ten reviews.
Do not wait for a pause that may not come. Google says it pauses new reviews on a profile when it sees a spike in spam, and that it tells the owner. It publishes no threshold, so you cannot know whether your wave qualifies. Report the clear breaches while you wait rather than instead of waiting. Our Google review removal work for health brands follows the same one-by-one method.
Watch for the banner. If Google does pause posting, consumers see a notice explaining why. That is Google's statement, not yours, and it is worth more than anything you write in a reply. Do not remove or contradict it.
The rest carries over. Do not bulk-report reviews that break no rule, because a report that fails teaches Google nothing and costs you the appeal. Do not run a counter-review drive. Reply once, in public, in general terms, and for a health brand confirm nothing about who the writer is.
The mistakes that make it worse
- Bulk flagging. Misuse, with penalties up to a Consumer Warning and a hidden TrustScore.
- Counter-review drives. Asking staff, friends or selected happy customers breaks Trustpilot's rules. Fake or incentivized reviews break the FTC's Consumer Review Rule.
- Arguing in replies. It feeds the thread and gets screenshotted.
- Legal threats sent by your own team. Groundless threats to get reviews removed are a violation of the FTC rule. If there is real defamation, speak to a defamation lawyer.
- Deleting your account. Trustpilot does not delete profiles. You would only lose the ability to reply and flag.
Our guide to Trustpilot's flagging misuse rules goes through the penalties in detail.
Where a removal service fits
A wave is when pacing and evidence matter most, and when a stressed team is most likely to flag everything. We sort the wave into reviews that break a rule and reviews that do not, build the evidence, and flag at a pace Trustpilot does not treat as misuse. We do not promise that any review will be removed.

Frequently asked questions
Trustpilot does not use the term in its guidelines. People use it for a sudden wave of negative reviews, often driven by a news story, a social media post or a coordinated group. Trustpilot's rules address the parts of it that break guidelines: reviews without a genuine experience, reviews about a trending topic, and fake reviews.
You should not. Trustpilot lists flagging reviews in bulk over a short period as misuse, because it suggests the reviews were targeted for their sentiment and not checked one by one. Source: Action We Take.
Trustpilot says every review is checked by automated detection technology before it appears, and that it removed 4.5 million fake reviews in 2024, 90% of them automatically. It may also add a Consumer Alert when a business is getting significant media attention. It does not publish how it handles a specific surge. Sources: Trust Report 2025 and Consumer Warnings and Alerts.
Google says that on a sudden spike in spam reviews it will remove the fake content, pause new reviews, alert the owner and show consumers a banner. It publishes no threshold for a spike and no duration for the pause. Source: New ways we're protecting businesses on Maps.
No. Google describes posting restrictions as something it decides and lifts on its own, with no route for a business to request one. Trustpilot publishes no equivalent mechanism at all. Yelp's alerts are also placed at Yelp's discretion. Source: Posting Restrictions.
Invite all customers in your normal, neutral way. Do not run a special campaign aimed at happy customers, do not ask staff or friends, and never offer anything in return. Selective invitations and incentives break Trustpilot's rules, and fake or incentivized reviews break the FTC's rule. Sources: Guidelines for Businesses and 16 CFR Part 465.
