This is incredibly funny even though I'm trying so hard not to laugh so I don't appear weird where I am now. Wait you mean someone can decide to pay people to vote for a contest open for the entire globe and in which winning is not even guaranteed? Such investment decision is worse than
these terrible historic investment decisions. I keep wondering where some of these hypothesis are coming from and why so much hypothesis for just a pizza contest. There is no perfect system of voting in the world and no matter how hard we try in this, there will always be room for improvement. Nevertheless, there will always be dissatisfied people no matter how fair a voting system is... those who feel they deserve to win but are unable to will always conjure something to discredit the voting system.
Hey, even if I didn't put enough salt, my pizza was very good. And I consumed it entirely the 6 following working hours!
And this was just an hipothesis,
So 1st: The submission was for 5 pizzas, not only one.. so financial impact is cushioned...
I dind't say that that was a mere "listing" to make paid votes, all the voters
and contestants (if Im not wrong) are from the same Local board..
So the real question is, What would make you (for a sympathy vote) make literally a completely copy paste of an whole exact shape, whom that btw cover all your vote allocations?!
So maybe there could be or not some dealings between them before ... but, yes.. regarding the number of the form users, alting etc., there could surrely be users that would do it even for very small reward!
This is stay an hypothesis, as it could be there an easier explenation:
All the users are part of the same acquaintances circle.. There is an user who manage the first to make the pizzas identification.. He send, or quote his own vote to the other users, so the other by just copy pasting !

PS: At this time, I have zero knowledge of whom the protagonists of this story are and neither which local board it is!
