That's an excellent question, and certainly in the world of corruption, because politically exposed people are so famous, it's almost universal to use an associate or an agent.
Banks commonly use commercial databases like World-Check. I don't know if you've heard of this. There are other ones as well. When a new client walks in the door, they run the name through this database. This database flags all kinds of fascinating information, including whether they're a relative or known to be an associate of a politically exposed person, whether they're on a sanctions list or they have criminal convictions—anything that's in the public domain. Thomson Reuters and different companies gather vast amounts of data, and it's quite expensive to have a subscription to that, but banks do this. They can certainly flag suspicious or red flags when an innocuous person walks into the bank. My hope would be that a registrar would do the same. You can't be sure, but it would create a red flag for enhanced due diligence, more inquiries and that sort of thing.
The other thing that's useful about a registry, especially if it has really good searchability, is that you can start to see certain patterns. For example, it's not uncommon for an agent working for a corrupt person to work for many corrupt people, and their name will start popping up more frequently, or you might have one address that has a surprising number of shell corporations associated with it. These patterns are almost impossible to detect, but if you get a large amount of data you can start to see suspicious areas.
I hope that's helpful.
