The player from Brazil had won over 20,000 after making a deposit but was then asked to deposit more money and refer an additional four people before he could withdraw his winnings. He had provided the link to the casino, however, we were unable to locate the casino as it wasn't listed on our website. We had informed the player that legitimate casinos should never ask for referrals and he may have fallen victim to a fraudulent scheme. We had advised him not to deposit any further balance into the casino and provided him with an article on how to choose a secure online casino. Unfortunately, we were unable to provide further assistance in this case.
