I've spotted this on several large events on setup day, explained how fucked they'll be in a few days and showed them a safe QR code generator. Usually it was just signage and they could reprint the QR code and glue it over the bad one, but one of them had printed hundreds of leaflets with the event schedule and I think they just ended up paying because even a year of "QR ransom" was cheaper than overnight printing and shipping.
My other favourite QR-code related fuckup is designers trimming the quet zone to just 1 module "because the white border looks ugly" and not checking if the codes are scannable. That and light-on-dark codes, which according to the standard don't exist, but most scanner apps can handle them these days thanks to endless complaining by designers.
