Once 75% of the votes are announce, a lynch deadline of 24 hours will be announced by the moderator. When that deadline is past, all votes are locked in place and the day's results will be announced.
This implies that 75% of people must be voting. 0% is not the same as 75%. Maybe you should make a ruleset you agree with instead of changing it in the middle of a game. I'm sorry if I'm sounding rude, but it's not really fair =/ ))
