I know multi account is against the TOS of a certain site, but what would happen if we make a new account because we lose access to our first account?
The intention is not to cheat the site, it's just that I love to gamble, I loss access to the old account so I created a new one.
I'd say when they mentioned in their terms of service that having multiple accounts is against rules, then even if your main account got a problem and you can not access it you should contact support and try to solve the issue that way, and if you did just that and your problem was not solved then why would you trust them again and create another account and deposit anything there anyways?
Can they use it as a reason to scam us though our intention is clean?
No, they can not, but if you act against their TOS they have the right to apply their rules as mentioned in their website.
Anyway this website is clearly scam and they probably waiting to get more money out of clueless people to fully exit scam one day.
