Thus its still best to provide our real information. However we have to be careful and be certain that the particular site can be trusted.
You misunderstood what I was trying to say here. I clearly mentioned that it's never a good idea to submit fake documents for the reasons that you specified, but I can understand why they submit them despite all the risks involved.
Also, it's common sense to only provide your KYC to trustworthy sites like Roobet, Stake etc.
Submitting your KYC documents is really risky and I would never do that as your privacy is in your hands and I am not comfortable with it but if you are submitting for playing then go through legit manners as these casinos have strict policies to freeze your account if they found something suspicious in your documents.
