Years ago in Argentina, a corrupt politician forced a small community to vote for them using a clever trick. They instructed the voters to fold their ballots into a specific shape or figure. Since the paper wasn't torn or damaged, the votes remained legally valid. This allowed the politician to ensure the exact number of promised votes were in the ballot box during the count

But votes aren't counted by how the paper is folded. Any one of the voters could stamp/mark another name (or no name at all) and still fold the paper as instructed. So, how does that work?

Because there was no unique ballot where you mark a name. Each party has it own ballot.
