It is a common thing to read and hear about casinos banning an account or restricting payment to an account because of the issue of multi accounting. Some gamblers will start a thread to that complain that they have only registered one account but still are accused of the issue of multi accounting. I am not saying they are all liars, but who do we trust here? Casino that has made the accusation or player who has been accused.
What exactly is multi accounting? and is it that some gamblers do not know when they are defaulting on that? Asides opening multiple accounts in a casino, what else can cause it because the gamblers are always claiming that they do not have another account, and the casinos are not always providing proof of the other account when they make the accusation.
Multi accounting is not a difficult thing to handle, but it will always involve the customer authenticating themselves by submitting KYC which crypto gamblers might not like. Everyone has an IP address and that is just one of the tools that can be used to track you. Some ISP's will share IP's between multiple users, which can make it difficult to distinguish them for the casinos, but they will generally only flag this behavior if there are lots of other red flags surrounding an account. Casinos know the common patterns, so if they get 20 people signing up from the same IP within a two day window, it's going to draw their attention - then they can view things like browser in use, screen dimensions, cookies stored and other fingerprinting which can flag someone who is not unique. This will trigger an investigation and all related accounts may end up having to prove they are different people.
