Casinos that require verifications after accepting a deposit without asking for anything or making big sign-up offers but don't write the full terms from the beginning are not among my favorites. It seems designed to trap you into putting your money in (this is always in the casino's interest) and being unable to withdraw it. Why would a casino do this and be considered tricky or sketchy?
As for anonymity, unfortunately for us who loved it, the days when we didn't need to do any kind of verification were long gone.
That's right, now we as good players rely on confining the KYC only to the most reliable and reputable casinos and although not everything is safe, a casino that is quite safe and reputable gives us the greatest peace of mind if we play there, what you say is very true, the anonymity is what we must take care of but not in casinos, but in our finances, those who have btc, crypto should not make the mistake of declaring them under any circumstances, because the government would already have a whole list of what we have and what we don't have, so it's not good, and if they realize that we play in a crypto casino the taxes must be huge.
