During the old days lots of things were easier to get.

Semi related to this - Ian Goldberg famously had the email address n@ai (Ian backwards if you missed it) - which caused problems for many mail clients and validators. I’d imagine cypherpunks.ca is easier to use. I saw similar things with one of the Balkans in 1998 - I think it was Croatia, where some government officials had name@hr email addresses.
