That isn't the way it is done, although you're correct in that one
usually proceeds by out-of-band communication methods, which get a lot
more attention than e-mails to abuse aliases.

In an age where identity theft is no longer even considered a high priority
unless the total exceeds $100K I seriously doubt that you could get them to
even talk to you about something like this, let alone send someone out to
investigate it!

Well, I've been there and done that, and I wasn't the one who was
surprised. As I've said, if you're doing something illegal, the mere
fact that you do it on the Internet won't necessarily protect you.
