That is the trick behind that KYC when they are trying to hide that asking but they will deliver once
you need to withdraw specially when you won a big cash amount , for me it is better to directly tell
people/gambler in their rules that they will seek KYC and that is truly tricky and not a best way to
deal for regular and legit gambler.
How do you know that? Up to now we haven't seen anyone complaining about an unexpected KYC request here, even less an issue about one he is not able to fill in order to withdraw his funds. Scammy casinos wouldn't stop their promotion because of abusers, they would lock their funds and ask endless KYC to the suspected users. In addition it's mostly sportsbooks that require KYC (to winning bettors), not casino-only platforms usually.
Maybe he think advance on any possibilities that this will happen soon since same as what other casino claims that they don't ask KYC but in long run or when needed to do some action they ask this. Also I guess Empire casino doesn't say something about they will not require this requirement. But rather what they write is no upfront KYC. so meaning if I'm not wrong they don't ask this upon registration, but when there's sudden changes they might require this. That's why its important to read the TOS so that we could able to know the real happening so no people will get surprised about possible KYC submission will asked to them in future especially if this is verification purposes.
