Hell no. Maybe it's childish, but I just assume every one of them is a Goatse link. Probably at least 40% of them actually are. While I was at SXSW this year, I realized how easy it would be to print up a bunch of QR codes that point to whatever terrible thing you prefer, and then paste them over the QR codes that are present on every single poster, sticker, etc. The QR code itself has no visual indication of what it is or what it links to, as opposed to a URL which does. Even if a URL shortener is used, the people who make the shortener can block redirects to spammy or offensive/illegal URLs.
