The Problem
Promos leak when identity is just an email
Abusers factory-fresh emails, SMS numbers, and payment methods faster than your KYC team can review. Rules based on IP or cookies collapse the moment someone opens a new browser profile.
The Solution
One device graph, many policies
LR Trace builds a stable device anchor; LR Insight surfaces clusters of related accounts; LR Intel adds known-abuse context. Apply limits at signup, redemption, and payout without blocking entire regions.
Duplicate detection at registration
Flag when a new signup shares hardware and environment signals with existing accounts—before the welcome email sends.
Promo and coupon guardrails
Bind codes to device risk tiers: single-use for suspicious clusters, higher limits only after verified history.
Referral graph analysis
Spot star-shaped invite patterns and velocity spikes that indicate coordinated farming, not organic sharing.
Incognito and fresh-profile resistance
Anchor identity below the storage layer so clearing cookies or switching browsers does not reset abuse budgets.
Analyst-friendly explainability
Show which accounts linked, when, and with what confidence—so trust & safety can overturn false positives quickly.
How It Works
Three steps to protection
Capture signals on signup and redemption
Instrument account creation, coupon apply, and wallet attach flows where abusers reveal themselves.
Cluster with Insight
LRDefender merges devices, IPs, and behavioral hints into a living graph you can query from your risk rules.
Automate proportional responses
Throttle rewards, require step-up verification, or block clusters—while leaving clean cohorts untouched.
Fund growth, not repeat abusers
