Voter manipulation is already a thing. Have a look at the Cambridge analytica documentary, The Great Hack, on Netflix. In one country, they did a campaign to convince young voters to not vote out of protest (now if you apply the tiniest bit of logic, not voting is the worst way to protest anything, you are letting the opposition win unopposed). But people fell for it and it swung the election against the targeted demographic. Victory for the manipulators. So yeah, it’s real. Aspects of the no campaign are using similar tactics with ‘don’t know vote no’, convincing people to give up their participation. Be very very wary of people trying to convince you of staying ‘unknowing’ or throwing away your vote. On any topic.
