Too risky?
I am asking myself: If I would be a cybercriminal and I knew something about "The Hive", would I then contact any of the US Authorities?
I have to admit, I think I probably would not. I would be too afraid to vanish into a dark hole; to me it seems this is the preferred method of all the Three Letter Agencies to obtain information.
So no thank you: I think I would keep my mouth tightly shut and stay anonymous.
Of course not being a cybercriminal in the first place is anyway the safer option :-)
