@holydarkness, you have a point, and certainly an interesting one.
But to answer your question, we do not upload nor store KYC data on our servers. We do not view or do anything with the information directly.
Rather, we use a third-party service called Veriff. [...]
Which you no longer has access, according to your own statement, or were you trying to say Veriff is an exception and you still have access to the service they offered?
[...] From this point, I no longer had access to any system or services. [...]
What is stopping you to send the email to the users existed with the version of database you have right now? Just a simple email blast, follow a few more to ensure everyone read the email. I will be checking my email.
Because for some reason, they can't decrypt it... apparently.
We can't send mass emails because they are encrypted, and no, before you ask, it is a one-way encryption.
