Common signs of an illegal online gambling operation include websites that ask for sensitive information such as social security numbers and bank account details, provide access to restricted gambling markets, offer rigged games that guarantee players will lose, and promise large sums of money with little to no effort required. These operations often operate in the dark web and require users to use cryptocurrencies for transactions to avoid detection by law enforcement agencies.
