Multi-accounting and Multi-device Fraud Prevention

Multi-accounting and multi-device fraud involve a single actor creating and managing multiple accounts across various devices to manipulate the platform. This behavior manifests in several sector-specific ways:

• Bonus Abuse
  Bonus Abuse is the most common scenario. During the onboarding process, fraudsters register dozens of fake profiles to exploit welcome bonuses or promotional coupons. This not only inflates acquisition metrics with fake users, but also drains marketing budgets, turning promotional campaigns into losses. These fraudulent patterns reveal themselves in the speed and repetitiveness of account creation and navigation, signs that behavioral analysis and device fingerprinting can reliably expose.
• Gnoming
  Gnoming (from gnome, like the mythical creature that hides in plain sight, highlighting the hidden and hard-to-detect nature of these fraudulent accounts) takes this further. Here, fake accounts are carefully disguised to look like they belong to different people: friends, family, or fictitious players. Gnoming is often used not just for promotions, but to manipulate betting outcomes. Because these accounts look unrelated, traditional monitoring often misses them. Only advanced behavioral analytics can detect the subtle connections.
• Collusion
  Collusion is another variation, in which multiple accounts controlled by the same actor sit at the same table or betting session. Sometimes every account is fake; other times, a genuine player unknowingly participates against a network of controlled identities. The aim is the same: to manipulate results. Transaction monitoring alone is not enough to reveal collusion, but behavioral analysis and fingerprinting can expose the hidden links.
