Well, this is indeed a very unusual request! A lot of casinos just stick to the basics when you sign up using automated systems to check for fraud.. they're okay with taking some risks at the start and only do a deeper KYC check if something sketchy pops up later. Many casinos keep it simple during sign-up, relying on automated fraud checks. They’re fine with taking some initial risks and only dive into a full KYC check if anything suspicious shows up later. It could also be taken as wasted time as someone mentioned already but then, we all know what they do with the personal data.. your data has a certain value to brokers so its not a waste of time afterall!

In rare cases, a casino might suspect the user’s request is unusual ( in your case, it is unusual! ) or part of a scam, leading them to avoid engaging preemptively in KYC.
