Apparently Chrome will now make a QR code of a page. I assume, but don’t know, that this means that taking a pic of the code then takes you to the page?
At which point, a QR code of goatse. To then plaster over the displayed QR codes of folks you don’t like.
OK, maybe not then. But that’s the sort of mischief which can’t possibly be original. So, where are those reports of folk littering fake QR codes around?
