The awkward thing is these ID’s that the user being submitted might be bought or hacked which means they can’t guarantee that the ID they are holding is from the user itself. Imo, submission of ID while your account is suspected for doing shady activities is very uncomfortable since you done know of the casino will plant evidence against you same case like this one.
Some casinos also have the condition of uploading documents with your selfie to tackle these issues and have heard on the forum that one of the casino is asking to upload street selfie also with sign boards but that's too much for me. The hackers and others might be using these bought ID documents but when suspicion arise and they ask for more your funds will be blocked with your account so it's better not to do such frauds.
