Nowadays there are lots of trusted casinos that have good reputations in the gambling industry so when we have suspicions about one of the shady casinos, there is no need to try to access it to play because it is very risky, especially giving KYC data because some casinos are shady will only abuse the KYC you provide.
If you have to provide personal data or other valid data to play gambling, of course you will also choose a casino that is trusted and has a good reputation.
The mistake of beginners is that they think that new casinos or small casinos can provide benefits, but in reality some of these casinos cannot be trusted and only harm gamblers.
Yes, I agree with you about choosing only reputable casinos for gambling. And if we have to do KYC, we can do it at a trusted casino because we believe the casino will not abuse our provided data. They can certainly take good care of it and will also protect their customer data.
Beginners can choose the casino well and won't choose it wrongly. But they are often tempted to try a new casino or a casino they already know is a scam casino because they see very attractive promotions. And that is the initial mistake of beginners that they must be well aware of so they don't make the same mistake again in the future.
There should be no other reason for a casino to refuse your KYC documents unless they are unclear, not readable, pictures aren't well taken, or there is something else that makes them not valid for the verification. If you submit documents that are valid, readable, not expired, having all corners visible, and you have taken the pictures with good lighting, the casino would never reject them unless they don't want to accept you in the first place.
The very first thing one should do when they get their documents and KYC rejected is they should check again if they have done everything right, if they are satisfied with what they did and think it's something from the casino, they should try another platform.
If the document we provide is valid and has been used to verify on other sites, it shouldn't be a problem for verification at the casino either. And when the casino still asks for other documents, the casino should also have no problems and can immediately approve our request for verification. But many people choose the wrong casino. They do KYC but are rejected by the casino for various reasons so they can do nothing but complain. If the casino is in this forum, they can complain and ask for help from us here to forward it to the casino representative. But if the casino isn't here, we won't do anything about it. Before verifying or registering at a casino, we should always check it more thoroughly, especially when we see information that requires us to do KYC so we won't have problems later.
