We’ve been seeing a lot of posts about multiple accounts using the same IP. When this happens, the casino will usually close the account, and worse, they might even confiscate the funds. As gamblers, we want to be honest and follow the TOS, but what if you’re living in a house where your family also loves to gamble and you all use the same site? Is it reasonable for the casino to close your account for multiple accounts, even though you didn’t actually create them, but because you share the same IP, that’s what they see?
This is certainly a very high risk.
Currently, casinos can even identify the devices that are connected to their site, distinguishing a smartphone from a desktop, and they can even obtain the browser version and operating system, thus speculating that they are from different people.
However, even a person who wants to obtain an illicit advantage could be using different devices for each of their accounts.
I used to be an RPG game operator (nothing to do with gambling) and there it was possible for users to voluntarily indicate that player A and B shared the same IP address and thus we could create certain restrictions within the game for these two accounts, avoiding undue advantages. Perhaps casinos can do the same.
