You're the only one with a post restriction after all, you could've came up with it, it's a possibility, isn't it? A Zexion lynch is more than justifiable in this scenario. Also, putting a post restriction in the game just to take it down after meeting certain requirements seems more than pointless to me and not fun at all.
Perhaps you were given the knowledge that lynching Zexion would end the day and it was you to figure out how to make that lynch happen.
