User, family and a couple others like myself who either intentionally or unintentionally use non-identifiable login credentials may not mind that much. Sarah Somethingorother might be real unhappy.
Temporary fix: Click the name on the first screen you see and edit it.
Side note - I don't mind Alpha bugs. This ain't my first rodeo. I don't mind sliding 30 feet off a flat surface to my death while trying to eat some beans. I don't mind character wipes.
However, I do mind when devs "alpha up" and create a problem where peoples' personal information is broadcast to the world. I'd mind it if I were testing the game for free. I sure as hell mind that these people paid $30 for the privilege of a colossal "alpha up" which leaked their private information.
