Blind CC is the weapon of choice in many organizations.
Oomg, I’ve seen so many weaponized BCC office-politics emails back in mt ofice day, it’s LOL-worthy.
People were BCC forwarding BCCs until at the end of the day, I’m quite sure everyone at that point saw the original email and subsiquent CCs and BCCs.
And Chuck Schumer must clean his gun with his tongue.
Back in the 1990s, I worked for a very large company, and they were just rolling-out email for the entire company.
Some random corporate announcement or email within some office in Malaysia or Brazil, would be responded to with a "reply all," send the message to every corporate email. Arguments would then erupt saying with some saying "don't use reply all!" - as they replied to everyone in the company.... I found it hilarious. It ended after about a year and a round of IT training for each employee.
BCC = passive aggressive.
It was valid until mid 80s.
