If he did, then they (Rollbit) believe that you are the same person. Most casinos prohibit multi-accounting, especially if one account was banned. Good luck convincing that he was your brother and you are you.
I also have a feeling that "tip" might have caused you some trouble. Again, maybe they think the tip sender and the receiver are the same person. We don't know for sure. Only you and Rollbit technical stuff know better.
the device i use is a pc and only a pc and its a new one to.
he never login from my pc cuz i didnt even seen him for a few month..
and about the ip he never login from my ip to but i might login ones or twice from my parents house which he was playing from there so thats what might be the issue i need razer here to check it all out..
and the tip i got was random from some diamond dude in chat that tip to a lot of people not just me so no issue there bro .
and i proved them i am not the same person by providing my id and driver license.. + live camera g..
i dont mind give them any info they want even my address g i just want to play on rollbit and have fun i didnt broke any rules g and i didnt even know my famliy member was banned until i got the ban and asked him
