Some people assume that there is no tampering with 'analog' votes. Entire boxes of votes disappear and get swapped by votes for the 'right' candidate.
It's a great initiative to do these public hackingattempts.
And imo there should be a very large sum of money attached for the ones who are able to break it. Voting is a basic human right in most countries and money should be spent in order for it to happen correctly.
