(iv) Suicidal - You require one less vote to lynch. This is not reflected in vote counts and does not affect Sadism.
Probably the easiest one for cultists to hide, since if you get to L-1, you're probably going to be lynched anyway. And it's safe because we can put people at L-1 and then discuss, and if they haven't declared suicidal, bam!
(v) Distraction - Your vote, once placed on another player, cannot revert to a player you voted to lynch earlier that Day.
Can be tested at the start of each day, although it's cumbersome, but who knows, we might catch one.
(vi) Paranoid - If at least one player has voted for you today, you may only vote players who have voted you today.
Can be tested, we get somebody towny to vote for everybody, and then we have other people try and vote for somebody else.
(ix) Sadism - You may only place your votes on players who are one or two votes away from a lynch.
Again, very easy to catch people at this one, and it should be tested.
I started to write about all the insanities, but then I realised I'm helping cultists choose good insanities, so I deleted it all except for the above.
All of these are things we can check for, in thread. Suicidal would be possible, but not practical, but we shouldn't be afraid of bringing people to L-1 if they haven't declared suicidal, because we might catch them out.
The other three can all be checked.
I ask that nobody vote during Day 4, until we discuss whether to start looking into these.
