It's really hard to lie about your SL account; 1st there is your Last Name (mine is a Retired Last Name), now some of you may know this but LL retires Last names after five years or so; 2nd is your Rez Date or SL Birth Date (mine is July 27, 2005). If you've been playing continuosly for how many years it shows in your profile too. Payment Info also tells if your a Camper or a Resident. Why anyone would want to appear younger than they are is beyond my grasp.
