Each department has its own shared email with more than a dozen people in it. When I started working here, I was wondering why we get over 100 spam and phishing emails everyday. One time, I reported an email. Next day, I got an email from headquarters, forced me to take this phishing training that takes 15 min. Training tells me to report it everytime I get phishing emails.
I thought it was a one time done thing. Nope. I reported again, and I had to do the exact training again.
So now I know why we have hundreds of shit emails. Because nobody wants to report them.
