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?
There is no hard and fast rule when it comes to situations like these because everything should rely on evidence presented by one (1) party.
Normally when a person accuses a gambling website of banning their account due to multiaccounting, the former must present evidence in order to controvert the same. The first step here would always be to
contact their customer representative to ask for details. Once their CS replies and tells you the nature of your ban, then you must provide screenshots or otherwise substantial proof that you are not really engaged into multi accounting.
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.
The reason on why multi accounting is prohibited is due to getting the bonuses offered by these gambling websites. Normally, they offer registration, deposit, and other bonuses to accounts. You can also check their ToS regarding their status against multi accounting.
