Protect your marketplace from fraudulent sellers and buyers

Two-sided trust is your product. When fake accounts, manipulated reviews, and ban evasion go unchecked, buyers leave and sellers lose confidence. LRDefender gives you a persistent view of who is behind each listing, message, and checkout — so you can enforce policy without punishing good users.

The Problem

Marketplaces scale abuse faster than manual reviews can catch it

Attackers spin up disposable accounts to shill products, manipulate ratings, and bypass seller bans. Fraud rings share tooling that defeats IP blocks and email verification — while your legitimate sellers pay the price in visibility and payouts.

Fake buyers and sellers use coordinated accounts to game discovery, coupons, and promotions.
Review fraud and listing spam erode trust — and create legal and brand risk when shoppers rely on manipulated ratings.
Ban evasion through new emails, devices, and browsers lets bad actors return the same day they are removed.
Bot-driven scraping and checkout automation distort inventory, pricing, and seller metrics.

The Solution

Link every account to real devices and risky infrastructure

Use LR Trace to recognize returning bad actors, LR Guard to stop scripted signups and bots, and LR Intel to surface IPs and patterns tied to known abuse — so trust & safety can act in minutes, not weeks.

Seller and buyer identity you can enforce

Stable device IDs help you tie multiple accounts to the same operator — essential for ban evasion, collusion rings, and payout fraud.

Stop automated review and listing farms

Behavioral and automation signals flag sessions that behave like scripts rather than shoppers or merchants at scale.

Friction tuned for conversion

Score risk in the background and step up only when signals cluster — keeping checkout and onboarding smooth for trusted users.

Faster trust & safety workflows

Give moderators device-level context next to each report so they spend time on real abuse, not duplicate tickets from the same root cause.

How It Works

Three steps to protection

1

Cover signup and listing flows

Instrument account creation, seller onboarding, listing edits, reviews, and checkout so you never rely on a single weak signal.

2

Detect rings and repeat offenders

Correlate devices and sessions with LR Trace; block automation with LR Guard; enrich with LR Intel for infrastructure tied to abuse.

3

Automate enforcement

Feed scores into your rules engine or moderation queues to shadow-ban, verify, or hold payouts before fraud scales across the marketplace.
