You could file a case with Action Fraud as well, I suppose. They're working on this. The more people they have testimonials from, the better.
Yes.
Guys, I can guarantee you that they are reading these boards. I even have proofs (though I have nothing to do with DeOS investigation, other than I created this thread and provided some evidences).
Good to hear they are still active on the investigation. I emailed the detective to see if I'd get an update but haven't heard back, which is what I expected.
