Obviously if Obama wanted to do a search and find out who is posting as “Resettozero” he can get the goods on you.
But for everyday use where some tree hugger doesn’t like your off’d deer pictures or your boss doesn’t like the fact that you called in sick but posted you and your friends on your Facebook page at the ballgame. Or your 3 year old riding your great dane and you post it so PETA can march in front of your house.
And more .... much more.
I stay off social networking myself
Keep my name between me and my closest friends/relatives.
No naivety there friend.
