How many times do we see stories like this? The casino allows players to win such big money, but the players are so lazy that they cannot separate their accounts with different email addresses, different IP addresses, and different devices.
You know that the casino is most interested in its money. They will look for the slightest mistakes in your communication. If you communicate with them as a woman but use the masculine gender, this will also cause them to mistrust you.
There is a rule: one house, one participant. Honest stories, showing dozens of documents from relatives, will not work.
