I don't know how someone technical could think the FBI cares about some random IP addresses visiting dark.fail. Do you also think the FBI uses their VB.NET GUI to cyberhack-backtrace this IP address list to arrest people for the pre-crime of looking for DDG's/BBC's .onion site?

Having a list of people who visited the site (possible via DNS records) is definitely a way to drastically narrow your suspect pool. Now you don't need to be a global passive adversary - you just sit on the links used by the "bad" people.
