I'll break my vow and say that posting "no vote" in the voting thread, (especially when its not even necessary to vote!) is behaviour that should not be encouraged/ carried on/ or taught to new players. It is entirely redundant and not beneficial to anyone, except assassins perhaps when they vote early. The only situation where it should be acceptable to cast a no vote is when someone has already voted someone else initially and decided against voting, in which case its not allowed to delete the post so thus they can change it to no vote.
What has been done has been done, but for future reference placing no vote as a vote should be discouraged, and can and will be a reason for people to vote on you.
