I worked for a Fortune 500 company in the 1990s. When the company first rolled-out email, and provided computers to many thousands of management and office staff, we would regularly see someone in a distant outpost in Malaysia, or India, or Eastern Europe hit “reply all” on a random email, sending it to everyone from the CEO on down
They would then get excoriated by some other random employee in another distant outpost, who would also send “reply all.”
It was quite funny - like some new form of electronic, global food fight. it happened fairly regularly in the first year.
Stopping it needed courses on “email use” and limiting global access to email directories for a lot of local offices.
That person who took it upon themself to excoriate the sender was named Karen and would come to screech at you to wear a mask. Via zoom, of course.
This happened even prior to email - I was on a Navy ship in 1987 that received a standard Navy message that was inadvertantly sent to the entire Navy distribution list. The subject line was something like ‘Designation of LT Amanda Jones as a Babe’.
The text then expounded on the female officer’s attributes. Have often wondered what happened to those who hit the wrong button to send it. It was hilarious to read while deployed.
