The most common techniques used in illegal online gambling operations include setting up offshore gambling websites to avoid legal scrutiny, using virtual private networks (VPNs) to hide the location of the servers and players, and accepting payments through cryptocurrencies to maintain anonymity. Additionally, some operators employ sophisticated fraud detection and prevention systems to identify and block suspicious players, while others engage in partnerships with organized crime groups to ensure protection and avoid law enforcement actions.
