Whenever there’s this discussion on HN, someone usually points out that can sometimes be a bother, especially when giving out the email in person, because people don’t really understand how email addresses works and ask “how did you get that email” or think you’re impersonating the service, or something similar.
I guess a solution might be to add the details sneakily. E.g. instead of linkedin@hnrobert42.com, saying robert_lkdn@hnrobert42.com
It also makes it easier to pass off a fake realname! Hi I'm John Smith, jsmith@oneofmydomains-nottooobvious.com...
You can even pick a domain sound like a legitimate mail service or company, e.g. jsmith@jgs-consulting.com.or jsmith@liberty-mail.io
All domains and addresses in this comment are fictitious - overlap with real domains is coincidental.
But that’s like 1:100 or so. And usually I’m entering my address to a robot so it’s not an issue.
