The whole thing remains me of my stint as a DM in a popular online multiplayer game. We'd get some guy who would play quietly for a few days, building up levels, and then suddenly, very carefully, he'd go on a rampage attacking newbies. Asked why, the answer was almost always, "Hello? Oh my god, my little brother got into my account again. I'm soooo sorry." The joke is that this same answer was given everytime. We'd just nod, tell them that they were banned from the game, and suggest they deal with "little brother."
