Small platforms are basically like this... Let me put it this way, the KYC of small exchanges in the crypto space is all transparent, and those small US stock trading platforms tied to crypto aren't much better either. I've shared before, hotel check-in info is the same. Those small, privately-owned hotels actually don't leak much info, but chain hotels or big hotels with HMS? Not only do many people within the hotel know, even the software service providers know. Check-in info gets mass-emailed to the marketing department.
