Does your casino have id verification when withdrawing winnings?
The moment you register with Roobet, you will have to fill out KYC form and yes before you withdraw it is required. Anyway, OP is not active anymore and you have to visit the site to confirm this. Roobet is a good site and one of the secure gambling site. Dont forget to read terms and conditions before trying this site, know if it works for you.
For the moment, Roobet is one of the only sites that you need to fill in some personal information when your register. But in the end, a lot of casinos require KYC when you want to withdraw some money (even small amounts). I have needed to complete a full KYC to withdraw 0.01 BTC.
This is the thing that we should deal in the future as we progress and promote adoption and regulation.
So far, details with Roobet are still safe but then again better not to keep any money to any site for a long period of time. If you are an active gambling then better. KYC is a good thing to secure the site and maybe this is why Roobet is still a good site and very secured. No regret filling out KYC with Roobet, its also fun to play.
