In your experience about casinos, have you seen any that show such evidence in the past? That seems like revealing sensitive information that people might learn to evade in the people. The problem is that many gamblers does not real the TOS of casinos, some do but deliberately chose to be obtuse. Most casinos state in their TOS that they have the right to terminate the account of anyone seen to be violating their TOS of which multiple account is one of. There are various mechanisms casinos us to confirmed multiple accounts and that is not what they can share in public. In conclusion, Rollbit is too big to scam someone of $1,263, that is not up to what they give away monthly in their X account.
There is a lot of excitement among those who gamble, due to which they do not waste their time reading ToS. Again, some people think that TOS of all casino sites is the same, due to which they do not feel the need to read the ToS of any previous site. And later when they face any problem, they start blaming the casino site. Gambling should always be done at one's own responsibility and not with a large amount of money, but only for fun, with a small amount of money that one can afford to lose. So that if they lose, they do not blame themselves or the gambling site.
