Ok I will assume that what u are telling so keep his account as it is...
Hi, what he means, is that atleast on vpn friendly casinos the ip match wouldn't be enough to proof a multi account (even if some people are little fool to think using a VPN would save). So that casinos use some extra tehniques such:
- deposit crypto addresses, bank accounts, cards.
- withdrawal crypto addresses, bank accounts, cards.
- caches
- hwid (depends on each casino)
, if you're detected by some of that reason as example you will be the target of a multi account acused.
Hope is not you're case and you will get this matter solved, good luck!
