I also can't link the second clue to the Ghost. But based on his behavior, he seems more like a negative player – he has that characteristic caution, as if he's trying not to reveal too much...

Yes, a good part of the list plays like that, if they play at all.

You can do whatever you want, but I wouldn't advise spreading votes.

I don't even know, playing Mafia without executions?
It's clear that a mistake will be the last one, but... dragging out the candidate for Non-Neutral for 3-4 days?
Leaving all the fun and the game to those who have Neutral Detective again?

Well, I don't know, on Olame, the clues from two days and selective amorality coincide well.
If the Master promises to modkill Olame, of course, I'll withdraw my vote.

Okay, but if, let's say, we didn't know his old nickname, what then?

But we do know, it's listed in his profile.
