I would highly suggest contacting the Oathkeepers. I've spoken with them before about something unrelated and understand that they have extremely good intel. They likely already have networked with drone hobbyists. As for myself, I tend to do things on my own, and I only play defense. I wouldn't go after someone unless there was a legitimate bounty. That being said, someone would need to be very stupid to come for me. They would not be walking away.
