Use critical thinking. No you don't cycle down a list. You say "hey I think your passport might have an extra letter r in it, you have another credit card, medical card, etc. I can take a look at?"
If anyone with a brain really thinks it's a forged passport they would skip straight to the whole "denying the transaction" part and reporting it through the banks reporting system.
This whole thread is a mind fuck of really dumb opinions. The cops just should not have been called.
They linked resources, forums, IRC, Matrix, and Discord. They listed some basic issues like client support, ui, etc.
This just feels like nitpicking. It's a bunch of people passionate about a project, doing it for absolutly nothing, seeing if others want to join in.
