I hadn't really heard much about this but apparently four out of five results returned when asking Google for a 'bitcoin qr generator' lead to scam websites. The sites then generated a QR code that encodes an address controlled by the scammers instead of the one necessary for the user.
Apparently instead of scammers making their own fake QR codes they have a blockchain explorer API to generate the QR for their address.
This scam falls into the reported $4 billion of digital currency stolen in Ciphertrace AML report.

I don't use QR code generators, and honestly, I usually type in the Bitcoin address instead of scanning a code, but there are many people that really use QR codes. 4 out of 5 is a terrible number, and this is the case we need cyberpolice for. Such crimes should not be left unpunished, scamming websites should not dominate the area. Or, another option, we need at least one trusted QR code generator for everyone to use and not worry about such things... I do agree with virasisog, though, that it does not mean Bitcoin is disappointing.
