It's hard to imagine why this is even a category tbh.
Especially if there is no good way of checking out the results. Just seems to not speak to this contest's integrity if people can just buy vote bots for a fraction of the prize money.

It's been in since the beginning and people enjoy it. It also provides marketing for the contest as a whole. We've thought about getting rid of it, but people like voting for their favorites.
And again, I did not say there is no way to check, I said there is no FOOLPROOF way to check. Any voting system will be able to be cheated without some form of voter registration tied to some kind of real life government documentation, the best way to catch people though is not to discuss how you can catch them.
