I've thought of QR-encoding the URL to the Rick Roll video and "pranking" people trying to scan ads.

Here come the righteous downvotes; to defend myself, I never went through with it, and they were ads to promote the city's iniative to invite the corrupt organization the International Olympic Committee so they could feast on our tax money.

A couple of years ago, I was bored at REI while waiting for something and decided to actually scan the NFC on the packaging of some sealskinz gloves. To my surprise, the NFC tag was still writable.

So, if you bought gloves at an REI in Bellevue Washington, and got rickrolled by the NFC packaging, that was me.

I think this would be a great way to educate the public about not trusting a QR code they find in public, without first double-checking it. Better than learning the hard way.
