Online gambling companies frequently use bonuses and welcome promotions to attract new customers, but these incentives have become targets for fraudsters engaging in new account fraud. This form of fraud involves creating multiple accounts, often with stolen identities, to exploit promotional offers without any intention of long-term engagement. Such fraudulent activities not only strain promotional budgets and skew marketing metrics but also negatively impact customer lifetime value and the gaming experience for legitimate users. The presence of fraudulent accounts can damage a platform's reputation, discourage genuine customer acquisition, and lead to stricter withdrawal requirements that alienate new users. Device intelligence, including browser and device fingerprinting, is a crucial tool for detecting and preventing repeat sign-ups, offering long-term visibility and accuracy in identifying fake accounts. The implementation of advanced fingerprinting technology helps gambling platforms maintain integrity by distinguishing between legitimate and fraudulent users, thereby protecting both their promotional investments and their user base.
