[Overwatch] How come the Junkers don't suspect Hammond of being an Omnic?

So now we know that Hammond is a hamster who escaped Horizon Lunar Colony. He landed at Junkertown and rebuilt his escape pod into a battle mech so he could fight in the Junkertown gladiator arena. He quickly became a champion of the fighting pits.

The Junkers do not know that Hammond is a hamster. They probably assume that he is just a human in a mech, but he has never shown his face or used his real voice, instead communicating with a computer voice. How would the extremely anti-Omnic Junkers not raise any questions about Hammond being just a machine and not a person inside a suit?

There's a lot of theories, but "intelligent kangaroo" has more supporters than "secretly an omnic" (best odds right now are on "radiation-damaged paraplegic on life support"). It mostly has to do with his movements, Omnics have a certain uncanny valley motion. He doesn't have the reflexes to be an Omnic and definitely behaves like a mech pilot. He also buys food and a few people think he's a vegetarian (they haven't noticed that he eats bugs too).
