Some common signs of an illegal online gambling operation include websites that operate without a license, accept payments through untraceable methods like Bitcoin, engage in money laundering, and target vulnerable individuals. These operations may also have connections to organized crime syndicates and may involve rigged games or unfair odds. It is important to note that engaging in illegal gambling is against the law and can lead to severe legal consequences.
