Im one of those people that submitted fake details for the lvl 1 KYC . Do not attempt to try this for anyone reading this, I mainly play with small amount of money in Roobet therefore I know that there wont be any problem regarding my account whenever I want to withdraw. I used to use my real identity for the lvl 1 KYC but I tried to change it before and Roobet wasnt even asking further verification about that so yeah staying anon with the fake details for now
unless if you are dealing with exchange then this is where real KYC or information is a must if you dont like problems but for gambling then it wont really be that necessary.
Its never been recommended but its up to you whether you do take risk or not and you know on what are the probabilities.
