Given the slim chances of randomness, I will exclude votes from those who look like copy/paste.
I'm sorry to say this, because I actually didn't contest and I have no interest in this, but inasmuch as such rule wasn't stated that users who vote for a particular sets of participants will lead to disqualification of votes, then I think it will be biased to now disqualify a certain groups of eligible voters. Because I'm pretty sure nobody forced these users to vote for the people they did, either it looking like a copy & paste or not. This can be discussed after winners have been announced.
Let’s discuss all those ideas after the closing of the contest, babo.
Rules for this editions were clear.
There is space for improvements? Sure, as in every aspect of life, but I think for respect of everyone, contestants, organiser and sponsors of this competition included, it is better to discuss change of rules after winners are announced!
Just my two cents.
You actually spoke well at Sir fillippone, because the rules for this year's Pizza contest were cleared to the understanding of everybody. So disqualifying some users will seems unfair, when it wasn't stated among the rules. Because the truth of the fact is that, the contest has already been organized, the eligible forum users have casted their votes, so what's left is for the winners to be announced. And if their is a need for change of rules, then that one can be discussed against next year's Bitcoin Pizza contest.
