I remember a couple of years ago I read up about the details on how QR codes are created. Specifically the masks that are added at the end to ensure that there aren’t any areas with too much whitespace or something that ends up inadvertently looking like the corner of a QR code (that square inside a square thing).
I've heard a decent argument why it should be avoided, and I'm curious to know to what degree. I understand avoiding .zip links, but should I go as far as to avoid .zip communities too? Where does this thinking become genuine paranoia?
