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.
Aside creating multiple accounts for real, there are several other factors that can or could lead to a user of a casino being accused of operating multiple account, and one of such factors is..
Connecting to the internet service of another gambler gambling on the same casino as you through Hotspot or other means, thereby meaning the two or more accounts are operating under the same ip address.
Another factor is using a free VPN which often comes with shared IP address to access the casino, if and when other people using the same VPN and with the same IP address accesses the same casino, all of the accounts involved can be tagged and their respective owners accused of operating multiple accounts.
This is the two factors I can tell for now, that often leads to casino accusing a user of multi-account even when the user isn't guilty of operating multiple accounts.
