What is the probability that, given 144 pizza options, 5 users from one local section vote for 5 identical pizzas, placing votes in the same order?
I didn't examine exact time when they all posted, but it's unlikely to happen if they posted exactly the same votes in totally different time.
I am not surprised to see cheating in this competition, and I remember something similar happened with voting in discord.
Gut feeling: this doesn't sound like a coincidence, it sounds like copy/pasting.
This is just a speculation, but it could happen that someone made an incentive and suggested this members should vote in exact same order.
Make your pizza, let people vote, if it's great you should get the reward. If people group up to vote, punish them because they don't work towards improving the contest but towards personal gain.
I think voting for anything is full of flaws, we can see that in political elections all the time.
Maybe we should have random pizza winners selected next time, after we first vote for worst pizza design
