One example would be state disability programs, they already need my real name and identity to work with me. Are there any downsides to sharing a simplelogin alias containing my real name vs no containing my real name? I just think it would be easier record keeping for them.
So that phishing attacks go to the one with your name in it that you don’t really use
Bots don’t know what’s a real name or fake. They’ll get delirious_owl@gmail.com from a list and phish with it no different than if JohnSmith@gmail.com was on the list.
delirious_owl@gmail.com doesn’t exist, though. JohnSmith@gmail.com does, and everybody wants to target it (both “bots” and humans too)
