How can I prevent people from finding and using codes from coupon sites that I didn't authorize?

Question

I'm struggling with unauthorized coupon code sharing on public websites and forums. These sites scrape and publish discount codes from various sources, which leads to uncontrolled discounting, revenue loss, and potential brand devaluation. My current discount strategies are being undermined by these third-party platforms, and I need a comprehensive approach to prevent code leakage and maintain the integrity of my promotional campaigns. How can I effectively combat coupon code distribution without alienating legitimate customers?

Preventing Unauthorized Coupon Site Code Leakage
Coupon sites (RetailMeNot, Honey, Rakuten) regularly scrape and publish discount codes they find shared on social media, emails, and review sites. Once a code appears on these sites, it gets far more redemptions than intended - often from customers who would have purchased at full price anyway, eroding your margin without driving incremental sales.

Growth Suite No-Code Approach
Growth Suite's Trigger Campaigns deliver discounts without shareable codes - the offer is triggered by visitor behavior and applied server-side, with no code for customers to share. There's nothing to post on Honey or RetailMeNot. The offer only works for the specific visitor session in which it was triggered, making coupon site leakage structurally impossible for Growth Suite campaigns.
