Most likely they're handled by a different group of people because if Roobet and Rollbit are actually related then Rollbit should've had the same KYC rules as well, I remember Roobet already require KYC but on Rollbit it isn't though.
I don't know why some people are so desperate to throw away some negativity when it comes to a question. It's either because they are living in such a shit community that they have been used to that. I was here to get confirmed whether these both are operated by the same or not. Why don't they get that it's in gambling discussion; not in reputation? Such poor people exist!
