There is no reason why blippy should have been able to expose credit card numbers to Google’s crawler. Any person who’s handled credit card numbers knows that this type of security problem is impossible to have if you’re PCI (Payment Card Industry) compliant.
Basically, it’s illegal to store credit card data unless you comply with PCI guidelines. In order to be PCI compliant, your PAN (Primary Account Number) must be encrypted and rendered unreadable, or you have to use a third-party to encrypt PANs for you.
The fact that users’ PANs were displayed in plain text is worrisome and suggests that blippy isn’t using the required strong encryption that would make them PCI compliant.
Blippy was always a disaster waiting to happen. That screwup may have been bad, but their brain-dead, tone-deaf response...
i didn’t like blippy from the moment i heard about them and this is exactly why.
