Well, this is Piratecraft. Mutiny was a part of life for any pirate.
Could we change the mechanism to a majority of leaders voting?
Or perhaps you begin the vote, and it takes place in a week, and if a leader doesn’t vote (due to being unactive) their vote simply isn’t counted. During this process the leader questioned would be unable to kick players.
We must, indeed, all hang together or, most assuredly, we shall all hang separately.
-Benjamin Franklin
