The questions marketplaces teams actually ask about automated abuse - answered directly, with the mechanics that matter.
Wishlist and watchlist counts look like soft signals, but bots farm them at scale to push weak listings up search results, mislead sellers about demand, and set up later scams.
Review hijacking reuses a well reviewed listing for a different product, letting copycat sellers inherit stars they never earned. Bots seed the early reviews and variation tricks do the rest.
Fake seller accounts are created in batches, aged with small legitimate sales, then flooded with counterfeit listings that harvest orders before trust and safety teams connect the accounts.
Fake review networks use aged buyer accounts, real purchases with refunded payments, and scripted praise to push weak products up marketplace rankings and bury honest sellers under ratings they did not earn.
Shipping label fraud uses stolen carrier accounts, edited labels, and counterfeit postage to move goods at a seller or carrier expense. The seller loses the product, then often pays the corrected postage and fees on top.
Brushing is when a seller, or a service acting for one, ships cheap unsolicited items to real addresses so the delivery creates a verified order history that fake reviews can attach to. Recipients did nothing wrong, and honest sellers get caught in the fallout.
Gift card payment scams move the real transaction off the marketplace. The buyer offers to pay by gift card, sends a code that is empty or stolen, and the seller ships before anyone checks the balance. This guide explains the variants sellers meet most often.
A hijacked seller account is worth more than a new one: it has history, reviews, and payout trust. Criminals take over marketplace seller accounts, change the bank details, list fast selling goods at tempting prices, and vanish with the payouts. This guide shows the sequence and the defences.
A hijacked seller account can drain payouts, change bank details, and burn years of reputation in a weekend. Takeovers usually start with a reused password or a convincing phishing message. This guide explains the attack path and the controls that break it before money moves.
A suppressed listing stops selling while the seller hunts for a reason that is rarely stated plainly. This guide covers how to find the real cause, fix the listing itself before appealing, write a short plan of action, and avoid the repeat violations that turn one suppression into an account problem.
An account health warning is a clock, not just a message. This guide explains how to read what the warning is really measuring, fix the root cause in your operation, and write an appeal or action plan that a reviewer can approve quickly.

When a listing falls in marketplace search, sellers often rewrite everything at once and learn nothing. This guide works through a calmer diagnosis: check indexing first, then traffic quality, stock and price history, and only then listing content, so each change can be tied to a result.
A payout hold feels personal, but marketplaces usually trigger it from patterns: a sales spike, a rise in late dispatch, new bank details, or a cluster of buyer claims. This guide explains the common triggers, the documents that clear a review fastest, and the habits that stop a short hold turning into a long reserve.
Most chargebacks are decided on paperwork, not on who is right. Sellers who save order, delivery, and communication records as they go can answer a dispute in minutes. This guide lists the evidence that actually moves decisions and how to file it so an investigator can follow it.
Fake tracking scams use a real tracking number for the wrong parcel, a label that is created and never shipped, or a number recycled from an old delivery. The buyer sees movement, the marketplace releases funds, and the goods never arrive. This guide explains the variants and the checks that expose them.
Triangulation fraud lists products the seller does not own, then buys them from a real store with a stolen card and ships them to the marketplace buyer. The buyer gets a genuine product, the real store gets the chargeback, and the marketplace seller keeps clean looking sales history.
Sponsored listings charge sellers per click, which makes ad clicks a thing worth stealing. Click bots inflate clicks on a rival's ads or run up costs on placements, wasting budget before real shoppers arrive.
Gift card draining bots test stolen card numbers and PINs at scale, check balances quietly, and spend or resell the value within hours. Marketplace sellers and shoppers both lose when a balance vanishes before the real owner uses it.
Price scraping bots copy your marketplace prices, stock levels, and listing changes in near real time, letting rival sellers undercut you automatically and steal the buy box before you notice.
Deal scalping bots watch marketplace deal pages around the clock, check out in seconds when prices drop, and relist the same stock at a markup before human buyers finish reading the offer.
Marketplace question and answer sections shape buying decisions. Bots flood them with planted answers that steer shoppers to copycat listings, discredit honest sellers, and bury real product warnings.
Fake flash-sale storefronts copy real marketplace listings, run a 48 hour sale at impossible prices, collect payment, and vanish before buyers or platforms can react.
Price-matching guarantees promise shoppers the lowest price, and bots have learned to manufacture fake lower prices, trigger automatic adjustments, and harvest the difference at scale.

A package you never ordered shows up at your door. Inside is cheap trinket you will throw away. The product was never the point: your address just became a verified purchase, and a five-star review is already live.
A wave of one-star reviews lands overnight, then the message arrives: pay up or it continues. How review extortion bots pick their targets and the playbook that shuts them down.
