If it was reported correctly, to me the conversation sounded more like an attempt to subvert Tor nodes and perhaps get access to the Tails developers and repositories or similar projects in the long run. Not that I know anything about this, but it may be better to counter such attempts not in an adversarial manner, but by playing such a dumb idiot and making so stupid jokes that they lose interest in you. Talk them down with irrelevant bullshit. After all, these kind of conversations really are sort of job interviews or attempts to intimidate to coerce cooperation, so any behavior is fine that would definitely spoil a job interview and make you unhirable. (Unless you want to work for them, of course...) Regarding the threat: well duh, you are doing something that might make you an accomplice of a crime (with whatever law they make) so yeah, they could arrest you then. How is that even surprising? Running a Tor exit node is probably not a crime in the Netherlands - I haven't checked on this. In any case, if it's a crime, it should maybe worry you that they also promised to protect the guy against police if he works for them. That's at least dubious. If on the other hand running an exit node is not a crime, which seems more likely to me, then the guy was really just threatening and harassing him.
