Maybe it'd be worth bringing this suggestion up to your employer, but I could see a value in making testing rooms that are effectively giant Faraday cages. It certainly wouldn't help against peer to peer network capable devices but it'd go a long way toward blocking cell/wifi. It's not like it's hard or expensive to construct a room in such a way to block such signals.

I am in nearly the exact same situation as you except that I am lucky enough to have never had my real name associated with my alias at the time. However, I did not avoid a criminal record as you obviously did. I'm pretty sure you knew exactly what you were doing at the time and that there were possible repercussions for your actions.
