I almost got taken in by a fake parking ticket scam, perfect ticket/envelope, the url printed on the ticket led to a 404 on the legitimate city website, the QR code led to a very convincing website/url, especially on mobile. The only reason I caught it was that I had gotten a legitimate ticket a month prior for parking too close to the fire hydrant and had marked the curb with chalk at the correct distance. So I tried to dispute the fine and discover that the ticket didn’t actually exist. And the city had no interest in the fake ticket whatsoever. They were just like “yeah, it happens all the time”.
