The most frustrating part had to be that ETH exchange uses a different risk scoring company, so even coins that are accepted on one exchange my not be accepted on another.
That's right, and by looking at both sites, I don't really see any big exchanges using them. Everyone seems to be using either ChainAnalysis KYT or Elliptic's Navigator, so I'm not sure how useful these numbers they're showing actually are, especially if they're not going to provide more details to understand why an address has such a score.
