hmmmmmmmmmm. i asked this ques only out of curiosity. when i first made my ID, i was unaware of this fact and used my real name(as we do on fb). but afterwards when i saw that nobody use their real name, i also became apprehensive and tried making a new id but for that i needed a new email id. then i thought of asking this ques, to know the real reason so that i can decide my further course of action.
