You should have spoiled the ballot.
As I understand it, those who claimed they voted Out in objection to the whole thing should have done the same, because those spoiled are still counted and because there's not an option for "neither, you lying bunch of cretins", so spoiling effectively registers that you have opinion and that your opinion is none of the options presented are what you want... so I'm told, anyway.
