Obviously, I saw an opportunity there to gamble with bigger amounts even if I do get limited. In case I did get limited, I just created a new account.
The problem start here, why you're not contact the live support first when your first account got limited, why you just directly create a new account? if they give you limit, this mean there's something on your account. I think Rollbit consider this act as "nefarious" since you're want to escape from the limit by create a new account.
I'd think Rollbit isn't wrong in this accusation, you're just greedy want to maximize your profit without think twice.
