> QR properly

I'm pretty sure that's the fault of terrible tooling being available to most people. No devices have built-in easy-to-find QR generating abilities, so to create a QR code most people end up searching the Web which is overrun with trashy URL-shortening-and-analytics services, freemium or paid, that wrap your link in their crap and make the URL expire or die with their fly-by-night website. Hackers know that it's possible and free to just make QR codes of the right type, and are able to find proper software to do it, but most people are throwing darts with the assistance of Google so they end up with crap usually.
