Iirc the way that blind works is by verifying you work at a specific company but then that email address cannot be used again.
It’s not associated with your specific account.
Someone who worked at blind explained that but there’s no way to know this for sure.
They don’t need to be a techie. Just someone who can click a button.
I am remembering Julian Assuage has/had a payload that was distributed via BitTorrent. The file was encrypted with a private key and his public key was posted either as a file in the package or on the site where the magnet file was downloaded.
Before he was arrested, he encouraged everyone to download the file and sit on it and to keep seeding it. He said in the event of his untimely death, the password would be released for everyone to decrypt.
That would be another option but you sort of need the notoriety to make this work.
