I see more cases appearing day after day with Stake Casino regarding the rejection of documents during the KYC process. However, each case is always handled by the team either by giving another chance, or at least given a valid reason for the permanent account disable.
In your case, this is not the first time you have encountered this issue with multiple other casinos, we can’t understand the reason yet. For me as a gambler in many casinos, I rarely even go through the KYC process. However, when I do get a request to upload my documents, even if one of my documents is rejected, the casino team always give me more chances and explanations to upload another document.

If this issue is appearing with you for the first time, it means you either broke one of the casino’s rules or you are on a blacklist in their KYC system.
