What's the policy for discount code sharing and abuse?

Question

I'm running an e-commerce store and struggling with customers sharing discount codes publicly, which is causing significant revenue loss. I've noticed codes being posted on coupon websites, shared in social media groups, and distributed beyond their intended audience. I need a comprehensive strategy to prevent code abuse, protect my margins, and maintain the integrity of my promotional campaigns while still offering genuine value to customers. What are the best practices for managing discount code distribution and preventing unauthorized sharing?

Policy for Discount Code Sharing and Abuse
Discount code abuse - sharing codes beyond their intended scope, using multiple accounts to redeem one-per-customer codes, or distributing behavioral offer codes to coupon sites - directly destroys campaign ROI. Prevention starts with code architecture, not policy enforcement.

Code Types and Sharing Risk

Code TypeSharing RiskTechnical Prevention

Generic promo code (SAVE10)Extreme - will appear on coupon sites within hoursUsage limits, short expiry windows
Exit-intent behavioral codeHigh - customers screenshot and shareUnique per-visitor codes with server-side expiry
Referral codeIntended to be shared - design for itLimit to X uses, track referrer LTV
Loyalty reward codeMedium - personalized to accountTie to account login, one-per-account

Technical vs. Policy Prevention
Policy enforcement (terms that prohibit sharing) is largely unenforceable. Technical prevention is the only reliable approach:

Unique codes per recipient (each customer gets a different code string)
Server-side expiry that actually deletes the code (not just hides the timer)
IP and email velocity checking for redemption anomalies
One-per-email restriction with duplicate account detection

Growth Suite generates unique per-visitor codes for all behavioral offers and deletes them server-side when timers expire. This makes sharing technically impossible - a shared code is already expired by the time it reaches a second person.
