1. The Inherent Vulnerabilities of Basic Referral Links
Naive referral links (?ref=code) suffer from attribution disputes, cookie stuffing exploits, and self-referral abuses. A production affiliate system requires cryptographic session tracking and fraud filters.
2. Multi-Touch Attribution Engine and Cookie Windowing
The attribution engine records timestamped touchpoints across configurable attribution windows (e.g., 30 days), supporting Last-Click, First-Click, and Linear multi-touch distribution models.
3. Anti-Fraud Verification and Device Fingerprinting
Automated fraud rules detect device fingerprint overlaps and billing surname similarities between referrers and buyers, disallowing self-referral abuses deterministically.
