I agree with yebellz that once someone came out as protector, the real protector would be forced to step out. There are three options:
Option A: The real protector came out in the first place. I believe this to have been a bad idea (because the protector cannot provide any useful information, and no one can protect the protector but themselves). If the protector is the only one that is known, then they don’t know who to protect. That seems like all of the drawbacks and none of the benefits.
Option B: It is a ruse by the robots. This is a high risk gambit, of course, as they would be out in the open. Once the ruse is discovered, they’re dead. That means it is most likely a strategic play to lure out the real protector; this seems a bad idea for them though, because is a 1:1 trade, and they’d go from 5:2 (150% disadvantage) to 4:1 (300%) disadvantage.
In this case, if the protector doesn’t come out, it becomes (to the rest of the players) indistinguishable from Scenario A, and we would all be sitting ducks.
Option C: Extremely unlikely and foolish, some other townsperson is claiming to be the protector. In this case, congratulations, they’re the real MVP protecting the protector. But this is indistinguishable from Scenario B, and would only work if they blindly trust each other, which they have a priori no reason to do. This has the worst odds to backfire terribly, if the real protector comes out meaning 1 innocent is killed by day, and the protector is a sitting duck by night.
I don’t think this is a good idea. That the protector did it, as I said, I think was a mistake. There’s no reason for everyone else to do the same and become a live shooting range.
EDIT: if no one else has come out by now, I guess she is the real protector.
