What is a brushing scam, and why do marketplace sellers get blamed for it?

Why a real delivery makes a fake review stronger

Marketplaces weight reviews from verified purchases far above unverified ones, and a verified purchase needs a real order delivered to a real address. Brushing manufactures that proof cheaply. The address is real, the tracking is real, and only the shopper's intent is fake, because there was no shopper at all.

Operators harvest addresses from breached data and public records, then ship low value goods in the seller's name. The recipient is a prop in the scheme, chosen because their address completes the paperwork the platform demands.

The harm spreads beyond the review itself

Recipients understandably worry their account or card was compromised, and some report the seller to the marketplace, the postal service, or regulators. A seller whose name is used by a brushing service they never hired can face complaints, investigations, and review removals while having no idea the shipments exist.

There is also a seed and biosecurity angle that made headlines in several countries: unsolicited plant seeds and similar goods raise agricultural concerns out of all proportion to their value, drawing in government agencies as well as platforms.

How brushing differs from a seller's own review scheme

Sometimes the seller is behind it, buying reputation. Sometimes a third party brushes a listing to harm it, knowing platforms punish manipulated reviews, or a rogue marketing contractor does it without telling the client what the promised review package actually involved. Motive matters for the outcome, but platforms investigate the pattern first and the story second.

Sellers should therefore treat any sudden set of verified reviews they cannot match to real demand as a warning sign, not a windfall, and report it before the platform finds it and assumes the simplest explanation.

What recipients and sellers should do

Recipients should not pay for, return at their own cost, or use unsolicited items they are unsure about, and in many places they may legally keep unsolicited goods. Checking account and card statements matters more than the parcel: if no charge exists, the address itself was the target, not the wallet.

Sellers who discover brushing tied to their storefront should document it, report it through seller support with order evidence, and audit any marketing contractor engaged in the same period. A prompt, documented report is the strongest protection when the platform's sweep arrives.

Why brushing survives enforcement

The economics remain kind to operators: worthless goods, cheap postage, and reviews that lift conversion across a whole catalog. Enforcement raises the cost by removing reviews and accounts in waves, but new storefronts are cheap too, which is why the practice fades and returns in cycles rather than ending.

For honest sellers the lesson is defensive. Reputation you did not build can be attached to you, used against you, and removed at your expense, so review monitoring is now part of basic storefront hygiene, not a vanity metric.
