Actually, Robin Hood robbed the tax collector and gave it BACK to the poor.
Protecting your idendity from thieves is one thing, but adopting a false identity in order to deceive is another thing entirely. Some people adopt an assumed name and an "alter-ego" in order to say things they'd never say as themselves. IMHO if it isn't good enough to say in the open it probably shouldn't be said in the dark either. My nic is PapaBear because KFG thinks thats what I sound like when I talk

, but my true identity is in my profile because I'm not ashamed to have my remarks assigned to me.
BTW, just because your a little paranoid it doesn't mean they aren't really watching you
