But then it is a different type of unfair. You'd then be saying in your opinion one video was better than what the "judge" said.
It is a lottery no matter what.
Put yourself in Anker's shoes:
- if they give a wide window of time, then those who submitted first get proportionally more votes than those last. So those who took time, say, to make the absolute best video of them all, and submitted last, would say it was unfair they had the best video but a worse one won through being rushed in lower quality earlier. So someone will say unfair.
- if they give a short window of time, those who had a video ready can win, those who need some time have no chance. So someone will say unfair.
- if they allow unlimited votes then a few people skew the result, so someone says unfair
- if you allow a vote a day, then the above time-based unfairness kicks in.
- you made Anker the judge then someone would just disagree on opinion of what is best.
There is no way you can avoid someone saying it unfair.
What Anker usually says is "congrats to the winner(s), and if you didnt win there are more opportunities in the future" so if you keep coming here eventually you will win.
