Common Fraud Types
Promotional fraud ranges from simple duplicate entries to sophisticated bot attacks attempting to guess valid codes or flood the system with receipt uploads.
OTP Verification
One-Time Passwords (OTP) via SMS are the first line of defense, verifying that a real human with a valid mobile number is behind the participation.
Anti-Bot Measures
Implementing rate limiting, CAPTCHA (smart or invisible), and IP reputation checks helps filter out automated traffic before it impacts your campaign database.
Validation Workflows
For high-value prizes, automated validation should always be backed by a manual review step or a secondary automated check (e.g., OCR confidence score).
Monitoring
Real-time anomaly detection is crucial. Systems should alert operators to spikes in traffic, unusual success rates, or patterns indicative of organized abuse.
