It is forbidden to create two or more accounts in legal online casinos. Multi-accounting is punished by operators: they can even block players and their deposits.
Such strict measures are caused by frequent improprieties on the part of customers. Users register multiple accounts to gain an advantage in the game. Another common reason is the theft of welcome bonuses that the online casino offers all new players.
Multi-accounting can be detected thanks to verification systems. Special tools compare accounts with personal data of gamblers, IP addresses, and other parameters. It is not possible to create several accounts with the same e-mail or IP.
