If you don't like such investigation results then we can move Technician into a Citizen category. That way, Investigators will only see an Android as itself. As you know, Android can't be killed or roleblocked, and while lynching the Android can stop his trolling and ability to vote, it doesn't stop the Technician from using Android to kill people. Keep in mind, a "lynched" Android is inactive during the day, but can still be controlled by Technician during the night.
