We absolutely cannot make this assumption, especially at this point in the game. If we don't vote correctly (not that I'm saying YesNo is definitely the correct vote), this game might be over for us. Rymuth could have stopped posting for any number of reasons- boredom due to being an Ordinary Rebel, boredom due to his UI partner swamped being killed, or real life and other games distracting him from his role as a Main Hutt. We simply can't know, and it would be totally irresponsible of us to take YesNo off of the list of suspects due to this assumption.
It's bad, I know. As I pointed out "yesterday", exchanging players so late in the game was a mistake, we should've killed Rymuth ourselves earlier.
It's the same for Palmer_v1 - even now that I have been identified as a his "target" I don't trust him 100%, he still could be the UI.
We can deinitely rule out Palmer (was targeted earlier in the game) and eJawa (cleared by Setre on N2 when the thief was active) as Main Hutt.
That leaves You, Matt Attack as well as me, raindoc and YesNO... and AbsoluteBro as candidates for the thief.
We need to narrow down that list and unless someone can provide new info we only have guesses left.
So let's guess: People have assumed that Rymuth left, because he didn't like his role and believe him to be the UI, because he was active on Day 1 but never seen again after the one UI was caught. Weak guess - but I also think that he would've been replaced earlier, if he had been one of "only" three Main Hutts. Hence going for YesNO seems undesirable for me at this point.
Doubting Palmer... like I said time and time again: I don't trust him 100%, but still more than others. His role claim seems valid, because it was really risky. If the true 2nd neutral (and a 2nd neutral role seems a good assumption) had role claimed or another Investigator had turned up it would have been all over for him. Furthermore, he's been friendly to me since early in the game, making people believe I was his target - had I flipped Hutt or UI it would've looked really bad for him...
So I'd say Palmer is probably telling the truth.
This, however, also makes me a less likely candidate for the Hutt or UI, not just because people feel that way, but because I am his (now confirmed) target.
So, we have (more or less) good reasons to believe that neither Palmer, Setre, YesNO or raindoc are the Thief, meaning it's either Matt Attack or AbsoluteBro.
