people can vote muliple times.
This poll has an anti-cheat system in place. You are not allowed to vote more than once. Even if you do, your votes will be discarded. Having said that, the system is not 100% solid. If someone is so determined to cheat, they could bypass it (let's not go into details how to cheat). But that is the problem of any Internet polls and the like. There is no sure-fire way to prevent this.
However I think the number of fraudulent votes should be low. Why?
Because I believe no single player is so ill-minded to cheat massively to twist the result.
Why do you want to do it anyway?
This poll is never official.
This poll didn't even get a sticky.
This poll has no actual effect.
Not that the developer said this poll would determine the fate of the ladders blah blah blah...
(If it were the case, it would have provided good incentive for any player from either side to cheat.)
It takes much time and effort to cheat, man!!
No one knows in advance it would be in the spotlight when the result was released.
It is possible the result thread draws litte attention, and is forgotten by the community after 1 day.
