OK, since BDex is on his way out the door, and I expect to the next one killed by the Legals, I wanted to throw out my suspicions so that my fellow humans can see what they think.
First, I think Manzcar and secbro are human - both have been after BDex, and their suspicions convinced me to investigate him.
That leaves 5, of which 2 are legal/robo:
Ivra
Frozenwind
Cillia
Destrus
Triumph
I am not feeling anything from Ivra, not sure about Triumph. The other three - if I get a chance, they are my next targets. Let me know what you think.
