Never attribute to malice what can be explained by ignorance? In this case I wonder if this was an intentional wide open doorway to fraud

I thought CAs automatically filtered out really low keys. There's a great Suckerpinch video ( https://youtu.be/M1si1y5lvkk ) about trying to purposely make the least secure HTTPS page possible, and Tom initially tried to choose a laughably-low number as the key, but the CA automatically rejected it.
