Initially they were there to offer richer error messages when the wrong code was scanned. However, we found that people were posting them publicly, misunderstanding the QR codes to be a kind of personal identifier. For one, this isn't useful because the QR codes, like safety numbers, are unique *per* conversation. So they aren't useful in a generic sense. And secondly this is bad because the QR code contains both parties phone numbers. // FREEBIE
