One of the most common ways to abuse online casinos is to create multiple accounts in order to receive bonuses, cashbacks or bypass limits. Along with this, bot accounts appear that automate behavior and imitate the actions of real players. Effective protection against these threats is a critical element of platform stability and integrity.
What is a multi-account and why fight it
Multiaccounting is the creation of multiple accounts by one user.
Objectives:- Receiving welcome bonuses multiple times
- Participation in promotions with fictitious profiles
- Partner Program Manipulation
- Bypassing limits and KYC
- Casino financial losses
- Violation of license terms
- Undermining the trust of honest players
Bot Accounts: Automating Fraud
Bots are scripts or applications that mimic the actions of a live user.
Signs:- High speed clicks or bets
- No mouse movement or interface interaction
- Activation at strict times
- Identical devices, IP, behavior
The goal is the pharming of bonuses, disruption of tournaments, fraud on partner tags.
