With polls now open we need to describe one of the changes in the voting mechanism this year.
Every year review the vote logs and voting patterns from previous years to fortify our defenses against manual and automated poll spamming. This year we've made changes to protect against a handful of savvy folks who take it upon themselves to try and ruin the fun for everyone else.
This year we've implemented additional defenses against poll spamming. We can't go into all the changes, but we do want to alert you to one change that may affect a subset of users.
If there are multiple computers voting in a home, work, or corporate environment those voters should avoid voting at the same time or one right after another. If you're not trying to cast votes in these situations simultaneously (or near simultaneously) then there shouldn't be any problem with them being counted.
Due to the sensitivity of this issue we can't really answer every question about our security measures, but know that we have multiple layers of security that are always balanced with providing open voting access to everyone. The result is a secure, enjoyable experience.
Again, the vast majority of voters will never notice, nor be affected, by these changes, nor will the system ever drop a vote that they cast. We just wanted to make sure everyone participating knows what's happening.
