Bonus abuse is fast becoming one of the most insidious threats in digital marketing. As businesses lean more into incentive-driven growth—through sign-up bonuses, referral rewards, and cashback offers—fraudsters exploit these programs to extract value without real intent to engage. In 2025, bonus abuse isn’t a fringe issue; it’s a core business risk threatening both budgets and metrics.
In this article, we dive into what bonus abuse is, the most common tactics in use, the real financial and operational fallout (with data), and how companies can defend themselves effectively—including modern solutions like GeeTest’s bot-management platform.
What Is Bonus Abuse?
Bonus abuse refers to the deliberate exploitation of promotional incentives—such as sign-up bonuses, referral rewards—through tactics that violate the intended fairness of the promotion. Unlike classic payment fraud, bonus abuse is often committed by real users using seemingly legitimate credentials, which makes it harder to detect and more damaging over time.
Bonus abuse typically involves:
- Multi-accounting: Creating numerous fake or duplicate accounts to repeatedly claim bonuses.
- Identity manipulation: Using disposable emails, virtual phone numbers, forged or synthetic credentials.
- Self-referral & referral farming: Abusers refer themselves or generate artificial referral networks to harvest rewards.
- Automated exploitation: Bots rapidly register accounts and trigger bonus events at scale.
- Device & environment spoofing: Fraudsters use emulators, VPNs, virtual machines, and device farms to appear as many unique users.
Modern abuse rings operate with industrial-level infrastructure, meaning a single fraudster can generate thousands of fake redemptions—undermining the economics of any incentive-based growth program.
Common Types of Bonus Abuse
Here are the main forms of bonus abuse seen in 2025, with the industries most affected by each type:
2.1 Sign-Up Bonus Abuse
- Fraud: Fraudsters repeatedly register new accounts—using temporary emails, SIM cards, or emulators—to claim welcome bonuses multiple times.
- Industries most impacted: Fintech / Neobanks, Gaming, E-commerce, Subscription services, Ride-hailing platforms.
2.2 Referral Bonus Abuse
- Fraud: Users self-refer or create networks of fake accounts to collect referral payouts. Often amplified by automation and device spoofing.
- Industries most impacted: Mobile Apps, Fintech, Wallets, SaaS, Marketplace platforms.
2.3 Deposit or Cashback Bonus Abuse
- Fraud: Abusers deposit minimal funds, instantly withdraw after receiving promotional credits, or repeat the process across multiple accounts.
- Industries most impacted: Online Gaming, Trading Platforms, Cryptocurrency Exchanges, Fintech.
2.4 Loyalty & Reward Points Abuse
- Fraud: Exploiting reward missions, stacking points, or manipulating loyalty systems to gain maximum rewards with minimal engagement.
- Industries most impacted: Travel & Hospitality, Retail Loyalty Programs, Subscription Services.
2.5 Coupon & Promo Code Abuse
- Fraud: While technically a different incentive, coupon abuse often intersects with bonus abuse: bots or scripts auto-apply codes, or users share single-use promo codes.
- Industries most impacted: E-commerce, Food Delivery, Subscription Businesses, SaaS.
Why Bonus Abuse Matters
Bonus abuse isn’t just “free money being given away”—it has deep, real-world consequences, and fraudsters today are highly sophisticated.
3.1 Business Impact
- Marketing budget drain: Fake accounts claiming welcome or referral bonuses directly eat into campaign spend. According to the Merchant Risk Council (MRC), first-party misuse (which includes bonus abuse) is a persistent problem in e-commerce. In its 2024 report, 62% of merchants reported an increase in first-party misuse.
- Growing share of global fraud: The LexisNexis Risk Solutions Cybercrime Report found first-party fraud (including bonus abuse) rose sharply in 2024, comprising 36% of all fraud globally.
- Operational costs: Fraud teams must spend more on manual reviews, customer support, and chargeback handling. According to MRC’s 2025 report, despite declines in some fraud types, first-party misuse remains a major threat.
- Deal distortion & metrics inflation: Bonus abuse skews key performance indicators (KPIs)—sign-ups, referrals, retention—giving a false impression of healthy growth.
- Reputation risk: As abuse grows, companies may tighten rules, reduce generosity, or cancel promotions, harming user experience and trust.
3.2 Attack Techniques (How Fraudsters Do It)
- Multi-accounting: Using device farms, virtual machines (VMs), or emulators to register many accounts.
- Device spoofing / fingerprinting evasion: Fraudsters pretend to be on different devices or environments to avoid detection.
- IP proxying: Using residential or data proxies to make traffic appear from many unique locations.
- Automation & bots: Scripts are used to register, perform tasks, and redeem bonuses instantly.
- Scripted human-like behavior: More advanced bots simulate realistic mouse movement or human timing to pass weak verification.
- Fraud infrastructure as a service: Third-party groups (fraud farms) offer set-ups to abuse bonus systems at scale.
These methods combined make bonus abuse not just a nuisance but a large-scale, industrialised business risk.
