For those interested, here's how the report looks.

There are 2 types of verification, 'standard risk check' and 'investigation'. Investigation scans in/out connections to find names
This type of check analyzes all incoming and outgoing connections with the address and finds among them cluster names (e.g., exchange's names). The results table contains the names of connections (clusters), their own risks and the number of intermediate addresses (distance to these clusters)
It works with BTC/BCH/ETH/LTC/TetherOmni
Here is their classification system

I have a question be the way: why ATMs are classified as ⚠ !
