Another one, guy sold his iPhone to a rep at the Verizon store. Rep didn't have him turn off Find my iPhone first. Months later, Verizon guy seller demanding the iCloud password to turn it off. Seller refuses, saying he'll call us to figure out how to do it. Seller didn't have a passcode. Verizon asshole Jamal sent a password reset to the phone since seller didn't erase the phone/sign out of email. Verizon rep gets password reset.
