Randomly generated domains are a major red flag for abuse and malware detection, and seems to have become a rather large part of how the domain industry manage abuse. Domain "credit score" is also something that is used in the email industry to score links and thus spam values. A large part of providing score values is behind security companies that offer their service as a paid services, but as with a lot of this stuff there are a lot of movement to offer it for free similar to spam block lists. It will be interesting when this kind of technology moves down to browser add-ons.
