How to Prevent Promo Abuse Fraud Before It Hurts Your Revenue

April 8, 2025

As promo abuse becomes more widespread, businesses struggle to protect the effectiveness and profitability of their marketing efforts.

In this article, you’ll discover what promotion abuse is and why it poses serious challenges for both marketplaces and their users. We’ll also explore the various ways promotions can be exploited, and how Blockify teams work to prevent and respond to this growing issue.

What is Promo Abuse?

Promo abuse means when customers or groups unfairly take advantage of promotional offers, discounts, or deals. They might do this by creating multiple accounts or using fake identities to keep claiming those benefits over and over again.

In fact, according to a 2022 report from Statista, this type of fraud was recognized by 30% of online merchants globally, based on a survey of approximately 1,000 merchants worldwide—as one of the most common types of attack. It ranked among the top five threats, alongside phishing, card testing, and identity theft.

What are Typical Forms of Promotion Abuse?

Promo abuse can take many forms, but some of the most frequent include:

  • Sign-up bonus exploitation: Individuals create fake or duplicate accounts to repeatedly take advantage of discounts or welcome offers meant for first-time customers.
  • Referral program manipulation: Fraudsters generate multiple fake profiles to refer themselves and collect referral rewards, appearing as though they’ve invited new users.
  • Coupon and voucher misuse: Promo codes meant for limited or single use are shared widely online or reused across multiple accounts to bypass restrictions.
  • Bypassing location-based restrictions: Some users use VPNs or proxy servers to unlock offers that are only available in specific countries or regions.

One of the most classic examples of promo abuse is the referral program by Tesla.

Tesla instituted the referral program in 2015, and it was used mainly to reward credits to members for the purchase of new vehicles or for the installation of EV chargers. Over the years, the program grew to encompass entries into high-end incentives such as factory tours, launches of new vehicles, and visits to Tesla and SpaceX offices.

This encouraged social media influencers to suddenly share their referral codes with their followers. Some even went as far as purchasing ads online, aggressively promoting their codes in hopes of accumulating rewards from referrals they did not personally make.

How Does Promo Abuse Affect Your Business?

Looks harmless at first; but believe me; eCommerce shops are going to face some severe issues due to this as it grows. Here’s the breakdown on how it can disturb:

Revenue Loss

When customers or even fraudsters take advantage of sign-up bonuses, referral rewards, or discount codes over and over, businesses end up giving away stuff without really getting anything back. Those little losses might not seem like a big deal at first, but they can really pile up, especially during those big promotional events, hitting your profit margins hard.

Reputation Damage

If customers see or hear about a bunch of promotion abuse, they might start to question how fair or trustworthy your brand is. Loyal customers could get frustrated if they think others are scoring “free rides” through shady tactics, which can chip away at their trust and ultimately hurt your brand’s reputation.

Increased Operational Costs

To keep the abuse at bay, businesses often have to shell out for fraud detection tools, tighter identity checks, or snazzier monitoring systems. These extra precautions can drive up costs and put a strain on customer service teams, especially if false alarms end up affecting your real customers.

How to Prevent Promo Abuse Fraud?

Preventing promo abuse starts with tightening your internal processes and being proactive. Let’s walk through the key steps to safeguard your campaigns effectively:

1. Test everything in a secure environment

Don’t wait until your promotion is live to find out there’s a loophole. Run tests in a staging environment that won’t interfere with your live systems.

  • Simulate real customer journeys, from cart to checkout
  • Try to break the system, enter expired codes, stack discounts, use fake accounts
  • Use test usernames and addresses to clearly label internal test orders
  • Notify your fulfillment team in case any test order reaches the payment stage

If a promo code fails these checks, it likely opens your campaign up to abuse or even point-of-sale issues. Fix these before going live.

2. Set strict terms and conditions for promotions

Your promotion’s terms and conditions are one of your strongest defenses against fraud. By carefully defining how, when, and under what circumstances an offer can be used, you can limit abuse without compromising the customer experience.

In addition to any legal requirements, make sure to include:

  • Limits on how many times a customer can redeem a code
  • Minimum spend requirements or caps on how much can be discounted
  • Exclusions for already-discounted items or certain products/services

Don’t over-explain your terms, fraudsters look for loopholes. For example, stating that cart abandonment discounts apply after five minutes gives them a clear trigger to exploit. These offers should nudge genuine buyers back, not reward manipulation.

Set strict terms and conditions for promotions

3. Control distribution and set time limits

Promo codes without expiration dates can cause long-term problems. Carefully defining how and when a promotion is distributed makes it easier to track and limit abuse.

  • Avoid evergreen codes, set clear end dates
  • Avoid sharing codes publicly unless access is limited (e.g., through login or user-specific codes)
  • Avoid using the same code in paid ads and social media, where it becomes accessible to anyone

For exclusive deals, distribute codes through:

  • Email newsletters to verified customers
  • Trusted affiliates who use trackable, limited-use codes
Control distribution and set time limits

4. Use smart tech to stay ahead

The right tools can help you strike a balance between campaign performance and fraud prevention.

  • Use behavior tracking to flag unusual activity
  • Adjust campaigns in real-time based on live data
  • Apply geolocation filters to limit access by region
  • Feed insights into your CRM to refine future promotions

5. Monitor activity throughout the campaign

Tracking only the final results means you could miss key signs of abuse along the way. Monitor interactions during the entire campaign lifecycle, including:

  • Failed promo code attempts
  • Increases in customer service tickets about codes
  • Abandoned carts after code entry
  • Chargebacks or review disputes tied to promotions

Consider setting up outreach triggers for high-value customers who abandon carts or fail to redeem a code. A quick follow-up can improve retention, and help spot abuse patterns early.

6. Use codes that are harder to guess

While simple codes are easier for users to remember, they’re also easy to guess and abuse.

  • For targeted or high-value offers, use randomized coupon codes with a mix of characters
  • Avoid using common phrases like “SAVE100” or “FREESHIP
  • For best protection, generate one-time-use codes tied to specific users
