I didn't know that and it is also impossible to verify whether they are independent or not. We all know how the three big ratings agencies did their job right before the financial crisis

They claimed to be independent, but obviously they weren't.
The one thing I really don't like and don't understand in ICObench is rating. There are several of so-called "experts" who have no idea about the tech behind blockchain and ICO. So they review projects and making grades for each project, but some of this experts are obviously don't know what these projects are about.
