Bonus abuse is no longer treated as a simple revenue-leakage problem. As of 2025, licensing authorities across multiple jurisdictions and acquiring banks are actively reviewing how operators detect, document and respond to systematic bonus exploitation, and gaps in these controls are triggering licence conditions, payment processor exits and enhanced due-diligence requests.
Why Regulators Have Shifted Their Focus
Historically, regulators concentrated on responsible gambling and AML obligations, treating bonus fraud as a commercial matter for operators to handle internally. That position has changed. Several European regulators now classify certain bonus abuse patterns, particularly those involving coordinated multi-accounting and money circulation, as potential indicators of financial crime. When a player exploits a welcome offer using synthetic identity documents and withdraws funds without generating genuine play, the transaction profile resembles low-level layering. Compliance officers must therefore treat repeat bonus exploitation as a risk signal that feeds into the broader AML framework, not only into fraud reporting.
The Controls Regulators Want to See
During licence renewals and routine supervisory reviews, regulators are asking for documented evidence of the following:
- Device and identity verification at registration: Operators should be able to demonstrate that each account is linked to a unique device fingerprint and a verified identity, with clear records of how duplicates are flagged.
- Velocity and pattern rules: Automated rules that detect unusual claim sequences, such as a player registering, claiming a no-deposit bonus, meeting a wagering threshold on low-margin games and immediately requesting withdrawal, must be written into the risk engine with defined thresholds and documented rationale.
- Behavioural analytics: Static rules alone are insufficient. Regulators increasingly expect operators to supplement rule-based systems with behavioural scoring that identifies coordinated ring behaviour across accounts that would otherwise appear unrelated.
- Audit trails: Every bonus restriction, account suspension or withdrawal delay linked to suspected abuse must be logged with the triggering reason, the reviewer who assessed it and the outcome. Regulators audit these logs to assess whether human oversight exists.
- Policy documentation: A written bonus abuse policy, reviewed at least annually, must define what constitutes abuse, the escalation path and the thresholds that trigger SAR consideration.
What Banking and Payment Partners Require
Acquiring banks and payment processors apply their own scrutiny, separate from regulatory expectations. When onboarding a new operator or reviewing an existing relationship, risk teams at acquiring banks look for chargeback ratios linked to bonus-related transactions. A high volume of first-deposit chargebacks, often a symptom of card testing combined with bonus harvesting, signals to a bank that fraud controls are inadequate. This can lead to reserve requirements, rolling holds on settlements or contract termination.
Beyond chargeback rates, banks conducting annual merchant reviews now request:
- Evidence that bonus terms are enforced at the transaction level, not only in terms and conditions documents.
- Data on the proportion of accounts that claim promotions and never return, as an indicator of professional bonus abuse activity.
- Confirmation that velocity controls exist at the payment method level, so that a single card or bank account cannot fund multiple bonus-eligible registrations.
Common Gaps Found in Operator Setups
In operational reviews, the most frequent weaknesses are not in the rules themselves but in the governance around them. Teams often build effective detection logic at launch and then allow it to drift as the product evolves and new promotion types are introduced. A free-spins campaign added by marketing six months after the original ruleset was written may not be covered by existing velocity checks. Regulators and auditors treat these gaps as evidence of inadequate ongoing oversight.
A second common gap is the absence of a clear link between the fraud team and the MLRO. When a bonus abuse case is escalated, there must be a defined handoff procedure that determines whether the case warrants a SAR filing. Without that procedure, operators risk either over-filing or, more dangerously, missing filings that a regulator later identifies as required.
Building a Defensible Programme
A defensible bonus abuse programme combines technical controls with governance structure. At OnlineShine, we advise operators to treat the documentation of their controls as equally important as the controls themselves. A regulator or bank that cannot understand how your system works, or cannot verify that it is working, will assume it is not adequate. Operators should aim to produce a concise control summary that a non-technical reviewer can follow, supported by system logs that confirm the rules are firing as documented.
A bonus abuse control that is not documented is, from a regulatory perspective, a control that does not exist.
Regular testing, including red-team exercises where staff attempt to exploit promotions using common abuse techniques, provides evidence of an active programme rather than a static policy. Scheduling these tests before major promotional periods, such as product launches or seasonal campaigns, demonstrates proactive risk management to both regulators and banking partners.
