I remember when I was working at the computer shop, and I had a guy bring in his old computer so his contents could be transferred to the new one I had sold him. Normally I didn't poke around in customer's files unless I had permission to figure out problems, but the names of some of the files I saw being copied over... had me really worried. Mentioned it to my boss and he said "you have to make sure." I had one finger on the phone ready to call my boss and the police in case if if had been child porn. Luckily it wasn't, but I wasn't happy to have to peruse someone else's gross stash.
