That's simply not true, Live. Votes definitely aren't locked by IP or anything other than account name, and you can definitely change your vote (although you can't remove them).

And no, you can't put any restrictions on a poll, just the title and options.

Regardless, we're after qualitative votes, not quantitative. Qualitative votes provide a lot more insight into why you think the person is fitting or, more importantly, not fitting for the role.
