What's odd to me is people are afraid of KYC so much. Why? Do any of you think that those evil people who want to steal you identity haven't done that yet? There are so many ways to do it besides asking about it openly on a gambling site, you can't imagine. Just relax, submit KYC level-1 and move, people. Live easier. 
You haven't experienced getting your KYC details hacked and spread across the internet which is why you have no idea how it feels. I do know how it feels since I saw a relative of mine get screwed because of his KYC details getting hacked. Think! Modern tech has made it tougher to safeguard our privacy these days which is why so many including me worry about submitting any form of KYC anywhere these days.
Lots of negative possibilities that might happen if our identity has been used for any illegal activity since we might suffer the consequences of what those criminals done that's why we should protect our identity so that no unimaginable bad incidents will happen to us. To many negative stories about stolen identity and for sure we cannot take the effect especially the crime committed by those criminals is huge that we can't imagine.
That's why its always good to be aware on the risk and we should protect our identity so that we can continue to do our activities without worrying on anything that we didn't do that's why people should always put in their heads that they should never submit their KYC details anywhere especially on those platform which reputation still questionable.
But incase of Roobet I think gamblers are fine here and we don't see anyone getting any issue related on this matter.
