Oh, you could catch them much more directly than that. There are technical means through which you can very easily track them down, if they make certain mistakes in their setup. On a non-technical side, it's often quite easy to social engineer people into giving you just enough information to track them (a kind of social equivalent to privilege escalation).
As part of another gig I worked on ways to track people, or more commonly to work out if two distinct users were actually the same human, and I'm almost salivating at the thought of all the potential ways authorities could bring some of these people to justice.
