The filling in votes thing was just kind of a threat to encourage people to vote in every match.
Let me take a moment to explain the desire for everyone to vote in every match (though, it's obvious that won't be happening, which I suppose is fine).
By having people vote in every match, it introduces an element of chance that is a part of any sort of tournament (see: NCAA basketball) or any sort of democratic process (see: People who don't know anything about politics voting for President). By having people voting in every chance, a very dynamic, unpredictable thing can happen that makes tournaments exciting (who doesn't enjoy seeing something like George Mason get to the Final Four or Barack Obama winning the Iowa caucus?).
Secondly, and less importantly, by having the same amount of votes for every match, it serves as an effective double-check for vote counting. If every match has 70 votes, and a match ends up 35 votes to 36 votes in your counting, you know you've done something wrong but, if all the matches have different vote counts, you may not realize the match is actually a tie until, I don't know, three rounds later when someone points it out and, oh shit, what are we going to do?
Anyway, there's the reasoning behind that rule, though it has become readily apparent that no one approves of it, which I was actually kind of shocked by.
Regardless, I started running the tournament to have fun doing it but, it seems as though the disconnect between my tournament-running style and the social dynamic of the board might be too far removed for either group to have a good time doing it. So, I think it would probably be better if someone else ran this? I think that everyone would have a better time that way. E Spaceman? scarred?
So, yeah. I hope you guys have a good time with this tournament. Good luck!
