That seems like it defeats the purpose though. Like if we say that "Cave Johnson" must be mafia, then nobody is going to claim him. Now if you aren't lying, they can just claim a random human test subject. Likewise, nobody would claim turret after our short conversation. Options for a fakeclaim are more limited there, but I could think of some.(which I won't share of course!)
Well at least this has spurred me to remember the third post of Stefl's that I didn't like.
