how about you accessing the gambling site and logging in from devices owned by people that you know, are you sure haven't done that? it is possible that you logged in on a device owned by someone you know who is also gambling in Rollbit and you just don't know it.

I am a little curious as to why they asked you whether your betting is influenced by outside force or made on your own.

anyway, I'll send Rollbuit Razer a PM about your case, maybe he can bring more information about your case.
