If TE uses his ability while robot votes are spread out, we don't gain as much information.
Actually I just thought of a plan... we hold a pseudovote every round. Whoever is lynched in the pseudovote, only the robots vote for them in the real vote. Everyone else votes for the person below them on the signup list (this means 1 extra person would vote for the that person probably). If the TE ever uses his ability, we will know who TE is because he will have been the only person to vote on the person that was lynched.
