:D Good point. I was thinking about unanimous votes and how they would leak information. Didn't want to over-complicate my comment, but I have a proposal for those too.
What I think we should do, is if the votes are close to unanimous as a matter of policy we report them only as "close to unanimous" without going into numbers. So for example if we have 100 delegates, and 95 voted for, and 5 against we just say "the vote was close to unanimous". And we do the same thing if the true vote was 100/0. All which would get published is that "the vote was close to unanimous", and the actual tally would get destroyed.
Maybe the threshold could be 10 people. So if the vote was 89/11 we would still publish that, but anything more one sided would just get reported as "close to unanimous" up to and including real unanimous votes.
It would still communicate the same thing: an overwhelming majority of delegates agreed on the thing being voted on. But would keep a fig-leaf of deniability for those who might otherwise be pressured.
That being said. I don't think people would vote unanimously on raising the minimum wage. Especially if the number of delegates is high (100 or above). You would get some people who either own a small business, or worry about the economy.
