Quick answer. “Black hat” is the seller term for tactics that break Amazon’s rules to gain an edge, either by inflating your own listings or by damaging a competitor’s. Amazon’s Seller Code of Conduct prohibits both directions. You may not manipulate reviews, sales rank, traffic or search results, and you may not attempt to damage or abuse another seller, their listings or their ratings. If you are the target, document the attack and report it through Report abuse in Seller Central with order IDs, ASINs and evidence, and keep your own account clean so the attack has nothing to attach to.
Most sellers meet black hat activity in one of two ways. Someone sells them a shortcut that turns out to be a policy violation, or someone uses one against them. The two cases need different responses, and Amazon treats the seller who bought the shortcut and the seller who was attacked in opposite ways. The sections below separate them, explain how Amazon finds manipulation, and set out what we would have you do on each side.
What Counts as Black Hat on Amazon
Amazon does not use the phrase. It writes rules, and black hat is the shorthand sellers use for breaking them on purpose for a commercial advantage. The useful test is direction. Some tactics push your own products up by faking demand, faking reviews or gaming search. Others push a competitor down by faking complaints, faking negative reviews or tampering with their listings. Amazon’s Seller Code of Conduct covers both, and its Customer Product Reviews policies add a separate zero-tolerance regime for anything that touches reviews.
Intent does not change the classification. A seller who hires an agency for “review generation” without asking how it works is still the seller whose account carries the violation. Amazon’s code lists allowing other people to act on your behalf in a way that violates its policies as an unfair activity, and the reviews policy states that employees and third-party partners count as the seller. The question Amazon asks is what happened on your account and your listings, not who pressed the button.
The Rules Amazon Applies
The Seller Code of Conduct requires sellers to act fairly and honestly. Among the examples of unfair activity Amazon lists are the following.
- Creating multiple detail pages for the same product or posting offensive product images.
- Manipulating sales rank, for example by accepting fake orders, orders you paid for, or orders refunded or discounted outside Amazon.
- Raising a product’s price after an order is confirmed.
- Inflating web traffic with bots or paid clicks.
- Inflating search ranking through keyword manipulation or by incentivizing customer searches to look organic.
- Attempting to damage another seller, their listings or ratings.
- Allowing other people to act on your behalf in a way that violates Amazon’s policies.
The Customer Product Reviews policies go further. Amazon prohibits offering compensation or free products for reviews, reviewing your own products or a competitor’s, using review services, asking buyers to change or remove reviews, diverting negative reviews to yourself while sending positive reviews to Amazon, and creating variation relationships to pool reviews from unrelated products. A family member or employee who reviews your product counts as a violation by you. The consequences Amazon lists are immediate and permanent withdrawal of selling privileges and withholding of funds, removal of all the product’s reviews with a block on future reviews, permanent delisting of the product, legal action including referral to civil and criminal enforcement authorities, and public disclosure of the seller’s name.
Common tactics and how Amazon rates them
| Tactic | Policy it breaks | How Amazon rates it |
|---|---|---|
| Buying reviews or offering incentives for reviews | Seller Code of Conduct, Customer Product Reviews policies | Critical (review solicitation) |
| Leaving fake negative reviews on a competitor | Seller Code of Conduct (damaging another seller, reviewing competitors’ products) | Critical (attempting to damage another seller) |
| Fake orders, self-purchases or bot traffic to raise rank | Seller Code of Conduct (manipulating sales rank and traffic) | Critical (manipulating search results or sales rank) |
| Filing false infringement reports against competitors | Seller Code of Conduct (agents and brand protection) | Selling account may be terminated |
| Inserts asking for positive reviews | Seller Code of Conduct, Communication guidelines | Critical (non-compliant inserts) |
| Creating duplicate detail pages | Seller Code of Conduct, product detail page rules | Policy violation on Account Health |
The Critical ratings come from the examples in Amazon’s Account Health Rating FAQ. Critical is the most serious severity on the Account Health page, and it carries the largest deduction from the rating.

How Amazon Detects Manipulation
Sellers who buy shortcuts usually assume they will not be noticed because the reviews look natural or the orders come from real accounts. Amazon’s published description of its review controls explains why that assumption fails. Amazon says it analyzes every product review before it is posted, using machine learning models and human investigators. When a customer starts a review, its models weigh signals such as ties to other accounts, abuse reports from customers, the reviewer’s history and sign-in activity. Language models look for wording that suggests an incentive such as a gift card or a free product. Graph neural networks map relationships between accounts to find coordinated groups.
The checks reach the physical product too. Amazon says its investigators may inspect products in fulfillment centers for package inserts that ask for reviews in exchange for compensation. An insert offering a gift card for a five-star review is a paper trail inside Amazon’s own building.
The scale is public. Amazon reports that it proactively blocked more than 200 million suspected fake reviews in 2022 and more than 250 million in 2023. It reports legal action against more than 150 bad actors in the US, China and Europe in 2023, and enforcement actions against thousands of bad actors that year, including revoked review permissions, suspended privileges, withheld or forfeited payments and blocked accounts.
Why bought reviews tie back to the seller
A review broker sits between the seller and the reviewers, and that is where the exposure comes from. Amazon’s lawsuits against brokers have sought disclosure of who hired them. In its 2022 action against Extreme Rebate, Amazon said it filed in the US and Germany to compel the broker to disclose who had hired it, so it could remove the resulting reviews that its own systems had not yet caught. A seller who paid a broker two years ago can surface in that disclosure today.
Offers That Look Like Services
Black hat tactics rarely arrive labeled. They come as growth packages, launch services or “ranking” programs. Amazon has described how the brokers it sues operate. They recruit reviewers through websites, social media and encrypted messaging apps. They offer money, free products or refunds in exchange for reviews. They sell fake positive reviews, fake negative reviews aimed at competitors and fake questions and answers. Some control customer accounts and post the reviews themselves. Some tell reviewers which keywords to search so the purchase looks organic. Some use Amazon’s logo to appear affiliated with Amazon.
Read any offer against that description. These are the pitches we see most often, and each maps to a written rule.
- Rebate or refund after review. The buyer pays full price on Amazon and receives a refund through PayPal or another channel once the review posts. This is compensation for a review, and the refund outside Amazon is also a sales rank manipulation example the code names.
- Search and buy campaigns. Buyers are told to search a specific keyword, scroll to your listing and purchase. The code prohibits incentivizing customer searches to look organic.
- Review swaps and groups. Sellers agree to review each other’s products. Each review is from a party with a financial interest, which the reviews policy and Community Guidelines prohibit.
- Variation merging. An agency adds your new product to an established variation family so it inherits the reviews. The reviews policy lists creating a variation relationship to aggregate reviews as a violation.
- Selective review requests. A follow-up tool asks buyers how their experience was and sends only happy buyers to the Amazon review page. Diverting negative reviews away from Amazon is prohibited.
- Competitor takedown packages. A service promises to remove a rival through complaints, negative reviews or test buys. That is attempting to damage another seller, with the risk resting on the account that paid for it.
The common feature is that the service provider bears little of the consequence. The seller who bought the package holds the account, the listings and the funds that Amazon acts on.
Attacks From Competitors
A competitor can file complaints, and Amazon acts on complaints it finds valid. Amazon also prohibits attempts to damage another seller and investigates reports of that conduct. In practice, the attacks we see fall into a handful of patterns, and each leaves a different trail.
Fake negative reviews
A cluster of one-star reviews lands within days, often from accounts with little history, sometimes repeating the same complaint in similar words. Amazon’s Community Guidelines bar anyone with a financial interest, including a competitor, from reviewing a product. Neither you nor Amazon can edit a customer’s review, so the route is reporting the reviews through the Report abuse link and, for a pattern, a Report abuse case in Seller Central with the review links, dates and the reasons you believe they are coordinated.
Manufactured complaints
Inauthentic, condition or safety complaints can be filed by anyone who places an order. One buyer account ordering, then filing an “inauthentic” claim, is a common opening move. Amazon treats inauthentic complaints seriously and may act on the account and related accounts, so the defense is evidence of supply rather than an argument about motive. Invoices that meet Amazon’s requirements answer the complaint itself. Order data showing the same buyer pattern across several ASINs supports a separate abuse report.
Listing tampering
An attacker can submit changes to a shared detail page, such as a new title, different images or an altered brand field, or can create duplicate pages that split your traffic. Brand Registry is the main control here because it gives the brand owner more say over what appears on pages carrying its brand. Our guide on defending your listings covers the hijacking side in detail.
Fake orders against your metrics
Orders placed and then cancelled, returned or disputed can pull on cancellation, return and defect numbers. Document the order IDs, the buyer accounts involved and the dates. The pattern across orders, not any single order, is what makes a report credible.
False Infringement Reports
One tactic deserves special attention. Amazon accepts infringement reports from brand protection agencies and agents, but its code of conduct says individuals with active selling accounts may not file infringement notices as a brand’s agent when doing so could benefit their own selling account, for example by removing competing listings. Amazon states that sellers filing notices to benefit themselves may have their selling account terminated.
A false notice still removes a listing until it is resolved, and intellectual property complaints count on the Account Health page. The first response is to contact the rights owner named in the notice and ask for a retraction if the claim is wrong. If the complainant is a competitor posing as an agent, say so in your report to Amazon and attach the evidence that connects them.
If you receive an infringement complaint you believe is false, see our guide on intellectual property complaints and our rights owner complaint service.
How to Report Black Hat Activity Against You
Amazon encourages sellers to report listing abuse and policy violations. Its Report a violation page gives the steps.
- Go to Report abuse in Seller Central.
- Select the violation type.
- Provide the order ID or ASIN or ISBN, as applicable.
- Describe the issue with the seller’s store or business name, the ASIN and product title, the stores affected, a concise explanation tied to the policy, and supporting documents such as order IDs or messages.
- Submit the report.
Amazon investigates every report but does not disclose results for privacy reasons. Abusive buyer feedback goes through Feedback Manager, and abusive buyer messages through Buyer Messages. Brand owners enrolled in Brand Registry also have the Report a Violation tool, which takes IP, store policy and regulatory compliance reports in one place.
What a strong abuse report contains
Name the policy first, in Amazon’s words, such as attempting to damage another seller or reviewing a competitor’s product. Then list the facts in date order with the ASIN, order IDs, review links and the store name of the seller you believe is responsible. State what connects the events, for example the same buyer account filing complaints on three of your ASINs within a week. Attach screenshots with visible dates and URLs. Leave out speculation about motive and anything you cannot show. One focused report per pattern is easier to act on than a long account of every grievance.
Not hearing back is normal. Keep a log of every report with the date and case ID, because the same record supports an appeal if the attack later affects your account.
When an Attack Has Already Hit Your Account
Amazon’s Account Health Rating runs from 0 to 1,000. Points come off for each policy violation by severity, Critical, High, Medium or Low, and come back when violations are addressed. A rating from 100 to 199 is At Risk. A rating of 99 or lower is Unhealthy, which Amazon describes as eligible for deactivation or already deactivated. Amazon also says it may deactivate immediately for suspected fraudulent, deceptive or illegal activity regardless of the score.
When a competitor’s complaint or review attack has produced a violation, the appeal works on two tracks.
- The violation itself. Answer the specific claim with evidence, such as supplier invoices for an inauthentic complaint or a rights owner’s retraction for an IP notice. Amazon decides the violation, not the attacker’s motive.
- The pattern behind it. File a separate Report abuse case documenting the attack and reference its case ID in your appeal. Keep this factual and short.
The most common error is writing an appeal that is mostly about the competitor. Amazon reads that as a seller who has not addressed the notice. The second most common error is admitting a root cause that did not happen in the hope of a faster reinstatement. A false admission becomes part of your account record.
First case versus repeat case
A seller with a clean history and a single complaint that is plainly false is in the strongest position. Evidence answers the claim, and the attack report explains the context. A seller whose account already shows unresolved violations is in a weaker one, because each new complaint adds to existing deductions, and repeat violations of the same policy reduce the rating faster. Resolve open items on the Account Health page before you need to.
When the shortcut was yours
If the violation came from a tactic you or your agency used, the appeal is a different document. It has to name what was done, when, by whom and how it was stopped, then show the controls that keep it from returning. Cancelled contracts, removed inserts, a list of the review requests that were sent and a named owner for compliance carry more weight than general promises. Amazon’s reviews policy describes permanent outcomes for review abuse, so these cases need the most careful handling of any we take.
If black hat activity has already led to a suspension, our Amazon suspension and reinstatement team can help you separate what you control from what was done to you and appeal accordingly.
US, UK and EU Law on Fake Reviews
Amazon’s rules are not the only exposure. Fake review conduct is regulated directly in the markets where most of our clients sell.
United States. The FTC’s Trade Regulation Rule on the Use of Consumer Reviews and Testimonials, 16 CFR Part 465, was published in August 2024. It prohibits fake or false reviews and testimonials, buying positive or negative reviews with incentives conditioned on sentiment, undisclosed insider reviews, company-controlled review sites posing as independent, review suppression through threats or intimidation, and buying or selling fake social media indicators. The FTC can seek civil penalties against knowing violators.
United Kingdom. Under the Digital Markets, Competition and Consumers Act 2024, the UK government states that fake reviews were banned from 6 April 2025, and businesses and platforms must take steps to prevent and remove fake reviews. The same reforms gave the Competition and Markets Authority power to enforce consumer law directly.
European Union. Directive (EU) 2019/2161 added to the Unfair Commercial Practices Directive a prohibition on submitting or commissioning false consumer reviews or endorsements, or misrepresenting reviews, to promote products. It also treats as material the information on whether and how a trader checks that published reviews come from consumers who used or bought the product.
The practical effect is that a review scheme can create liability outside Amazon even after the account issue is resolved.
How to Protect Your Business
Protection is mostly preparation. An attack is cheap to launch and expensive to answer if your records are scattered or your account already carries violations.
- Keep your own account clean. An attacker’s complaint lands harder on an account with existing violations. Address items on your Account Health page promptly.
- Register your brand. Brand Registry requires a pending or registered trademark for your brand name or logo from a government trademark office in a country with an Amazon store. It adds Report a Violation, and eligible brands can use Project Zero to remove listings and Transparency serial codes to authenticate units.
- Keep supplier records ready. Fake authenticity complaints are answered with invoices that meet Amazon’s requirements. Store them by ASIN so you can respond the day a complaint arrives.
- Monitor your listings and reviews. Sudden spikes in negative reviews, new offers or changed content are worth documenting with dates and screenshots. A weekly check of your top ASINs catches most tampering early.
- Vet anyone acting on your behalf. Amazon holds you responsible for people who act for you in a way that violates its policies, including agencies and service providers. Ask each provider in writing how it generates reviews, traffic and rank, and put a prohibition on review incentives and complaint filing into the contract.
- Use only Amazon’s review tools. The Request a Review button and Amazon’s own programs ask every buyer in the same neutral way, which keeps you outside the selective request and incentive rules.
- Say no to shortcuts. Offers of guaranteed reviews, rank boosts or competitor takedowns describe exactly what the code of conduct prohibits.
Mistakes that make an attack worse
- Retaliating. Reporting a competitor’s listings without evidence, or leaving reviews on their products, puts you in the same violation category as the attacker.
- Contacting the attacker off Amazon. Threats or demands sent outside Amazon create a record against you and do not stop the complaints.
- Offering buyers refunds to remove reviews. Asking a reviewer to change or remove a review, including in exchange for a refund, is prohibited even when the review is unfair.
- Ignoring small notices. A single listing removal answered late can become the violation that pushes a weakened rating into At Risk.

Frequently Asked Questions
What is black hat on Amazon?
It is a seller term for tactics that break Amazon’s rules to gain an advantage, such as fake reviews, rank manipulation, keyword search campaigns or attacks on competitors’ listings. Amazon prohibits all of them under the Seller Code of Conduct and its reviews policies.
Can a competitor get my Amazon account suspended?
A competitor can file complaints, and Amazon acts on complaints it finds valid. Amazon prohibits attempts to damage another seller and investigates reports of that conduct. Clean records, supplier invoices and a healthy rating make false complaints far easier to answer.
How do I report a seller for black hat tactics?
Use Report abuse in Seller Central with the violation type, order ID or ASIN, and a concise explanation backed by evidence. Brand owners in Brand Registry can also use the Report a Violation tool.
Will Amazon tell me what happened to my report?
No. Amazon says results of its investigations are not disclosed for privacy reasons. Keep the case ID so you can reference it later.
Am I responsible if an agency I hired breaks the rules?
Yes. Amazon’s code of conduct lists allowing other people to act on your behalf in a way that violates its policies as an unfair activity, and the reviews policy treats employees and third-party partners as the seller.
