Are you going to learn from that and change your ways?
There was lots of flatly false and misleading crap coming from the Remain camp as well. Just look at how Cameron see-sawed on the consequences of an exit. Before his negotiation it was "things will be OK even if we leave, the economy is fundamentally strong". Then it was chaos, doom, "economic self harm", permanently worse off etc. Now the vote went against him it's back to "everything will be fine".
When the leader of the campaign can't even stay consistent on such a basic thing, that campaign cannot claim a monopoly on truth.
Misinformation, fear campaign, memes, troll farms. It seems in social media age that's how you do politics. Viral marketing means you never have to say you were wrong.
But you are mistaken in blaming the electorate. The "misinformation, fear campaign, memes..." have always been around. The primary reason people voted out the previous bunch is corruption and tunneling of the wealth created to a narrow group of people (a problem not limited to Poland only)
