Why have the hidden profile option?

Wasn't there a user on here once that stole someones identity?

Maybe some people only want their friends to be able to comment and view their page, Plus when you get banned you get bombarded with users you've never talked to adding their 2 cents xD

 

Maybe in that case it's a question of what should be hidden then rather than a blanket over the entire profile.  I can understand not wanting people you don't know posting on your wall but it seems given we have friend list its not a hard piece of coding to have a restrict wall to friends option.
