I think his explanation of trying to make the lynch go away until it looked near-certain makes sense. I'm not positive Robz is town, but lynching power roles kind of sucks.
FWIW, I -never- believe PR claims, dating all the way back to M-III, when I got lynched because I called Joth's PR claim an obvscum fake and people prosecuted me for pushing a lynch on a claimed PR.
Of course, I was town and Joth was scum, but that's irrelevant.
Robz is wrong that I would've lied. I would ask him to point back to a single game where I've ever fake-claimed, or lied about what I actually was in ANY facet. I was lynched as VT in M-III. Lynched as VT in M-IV. Not lynched as a claimed WOSV in M-VI. Lynched as a VT in M-VII. Not lynched as a VT in M-VIII. NK'd as a One-Way-Lover in M-IX (late in the game, getting myself intentionally NK'd to leave ABirds alive). NK'd as VT in M-XI. Didn't fake-claim in ZM-1, or M-II as scum (would've claimed VT in both though).
So no, I would not "do the same thing in his position". I would refuse to claim, but once intent to hammer came out, I would've claimed truthfully. Especially at/near deadline, so that we had time to actually move our votes around to somebody different. I certainly would NOT have dragged it out until deadline-1hour, then claimed "Oh wait, I lied, I'm actually a PR!", pushing the entire town into quick/no lynch territory. I think it's absolutely a scum power play for a no-lynch or bad lynch. If it IS town play, it's very poorly done town play because he gave us very little to no time at all to readjust. So quite simply, I won't.
