At work, people (and programs!) using email who mistakenly type subjects containing the word “page” into the “To:” or “Cc:” line instead of the “Subject:” line end up sending me email. Given the nature of our business, the word “page” comes up frequently in emails.
I never reply to these, just delete them. But I see some strange stuff.
At a previous company, a co-worker had the user name “asdf” .. he once got a confession of infidelity. Delete!
Back when the Web was young, Brian Behlendorf had (if I remember correctly) nowhere.com. He got lots of interesting email to user ”nobody“ at that address. And would reply to it.
