Incentivized reviews

Offering money, a discount, a free or discounted product, or any other benefit in exchange for a review — even if you ask for an "honest" review regardless of outcome. Marketplaces treat the incentive itself as the violation, independent of whether the resulting review is positive or negative. This also covers indirect incentives: entering reviewers into a giveaway, offering loyalty points, or providing early/free access specifically framed around leaving feedback.

Review gating

Asking for reviews only from buyers pre-screened as likely to be satisfied (for example, sending a "how did we do?" survey first and only inviting satisfied respondents to leave a public review). This creates an artificially inflated rating by filtering out likely-negative reviewers before they reach the public review system. A subtler version of this is routing dissatisfied customers toward private customer service exclusively, while routing satisfied customers toward the public review page — the line between legitimate customer service triage and gating can be thin, so the safer practice is inviting everyone to the public review path and separately, always, offering a private support channel to anyone with an issue.

Brushing

A scheme where a seller ships low-cost or empty packages to real addresses (often obtained without the recipient's knowledge) in order to generate "verified purchase" status, which is then used to post fake reviews on the seller's own listings. This is treated as a serious violation and, in some jurisdictions, is associated with broader fraud enforcement actions — not just a marketplace policy issue. Recipients of brushing packages they never ordered should report it through the marketplace's reporting channel; sellers should never engage a third party who proposes running this kind of scheme, no matter how it's framed.

Fake or paid reviews through third parties

Using a review-exchange service, a private Facebook group, or a paid reviewer network to generate reviews disguised as organic. Marketplaces actively invest in detection systems for these networks, and enforcement has increased substantially over recent years as this became a known problem. Detection methods commonly include cross-referencing reviewer account patterns, device/IP overlap, unnatural review timing clusters, and text-similarity analysis across reviews and reviewer histories.

Sockpuppet / associated-account reviews

Using a secondary personal account, a family member's account, or an employee's account to review your own product (positively) or a competitor's product (negatively). Marketplaces look for account relationship signals — shared payment methods, shared devices, shared shipping addresses — to detect this, and it's treated as a serious trust-and-safety violation rather than a minor policy infraction.

What actually happens when caught

Consequences scale with severity and repetition:

  • Review removal — the affected reviews are taken down, sometimes along with other reviews the same reviewer account left.
  • Formal policy violation notice on your account (see What Happens When Your Account Health Drops).
  • Listing-level suspension — the specific ASIN/listing tied to the violation is removed from sale.
  • Account-level suspension — for serious or repeated violations, the entire selling account can be suspended, which is a materially larger consequence than a single listing issue.
  • Withheld funds — pending balances can be held during an investigation into suspected manipulation.
  • Legal/regulatory exposure — in serious cases (particularly brushing schemes involving unauthorized use of real people's shipping information), consequences can extend beyond the marketplace itself into broader consumer-protection or fraud enforcement.

Because review manipulation is treated as a trust-and-safety issue rather than a simple performance metric, appeals require a genuine, documented change in practice — see How to Write an Effective Plan of Action. A plan of action for a review-manipulation violation typically needs to address root cause (how it happened, including any third party involved), immediate corrective action, and preventive measures going forward — a generic or vague response is unlikely to succeed given how seriously these violations are treated.

How to protect yourself even when you didn't do it

Sellers occasionally become victims of review manipulation aimed at them rather than by them — a competitor leaving fake negative reviews, or an unscrupulous former agency continuing tactics after being let go. If you suspect this:

  • Document the pattern (timing, account characteristics, review content similarities) as specifically as you can.
  • Report through the marketplace's official abuse/policy violation reporting channel rather than only responding publicly to the reviews themselves.
  • Keep your own practices demonstrably clean, since an investigation into suspicious review activity on your listing can sometimes scrutinize your own review history as part of the process.

Mistakes to avoid

  • Assuming a practice is safe because a supplier or agency recommends it — the seller's account bears the consequence, not the third party's.
  • Believing "honest reviews only" framing makes an incentive acceptable — the incentive itself is the violation.
  • Continuing to work with a review-management vendor after learning they use gating or incentivized tactics, even if you didn't request those specific tactics.
  • Treating a single review-removal notice as a minor issue rather than an early warning sign to audit your entire review-generation process.

FAQ

If my agency did this without my knowledge, am I still responsible? Yes — marketplaces hold the selling account responsible for violations regardless of whether a seller, an employee, or a contracted third party carried them out. This is exactly why vetting any review-management vendor's actual practices matters.

Can I get flagged for review manipulation I didn't intend, like an overly enthusiastic post-purchase email? A poorly worded but non-incentivized, ungated request is unlikely to trigger enforcement on its own, but review your message templates against the specific prohibited practices above to be sure they don't inadvertently cross a line (implying a benefit, conditioning the ask, or selectively targeting likely-positive reviewers).

What should I do if I receive an unsolicited "brushing" package? Report it through the marketplace's official channel rather than ignoring it — brushing schemes use real people's information without consent, and marketplaces want these reports to help identify the sellers or networks responsible.
